Interesting video about ball motion and balling up and down

[JasonNJ]

Found this on YouTube and I thought it was interesting. From what I can tell balling up means an earlier rolling ball and balling down is a later rolling. I wanted to see what some of the more experienced guys thought of this video.

This is an incredible video! Watching the ball go through the pins is one of the most important things that a bowler can learn to do as it can give you an indication of what moves and/or ball changes are required BEFORE you start leaving ugly splits. I particularly liked the part at the end of the video where it explained that certain leaves can be avoided by balling up OR balling down. This has to do with the development of what I have called the "Dead Zone," and Joe Sloinski called "El Diablo," in separate articles in BTM. Most bowlers assume that as the lanes start to dry out, the only change is to ball down, when, in fact, there are other options.

[JasonNJ]

Yeah I think this video was pretty awesome and one of the best I've seen explaining the motion through the pin deck. Something I need to train myself to do better.

[RobLV1]

Hand in hand with watching the ball exit the pins is learning to check the rack before each frame that you bowl. Once you are aware of how the ball is going through the pins, it's pretty easy to see how having pins off spot can affect pin carry. In the PBA, bowlers are allowed two re-racks each game, and re-racking must be the first order of business... before they even pick up their balls off of the ball return. The USBC is much more lax, allowing unlimited re-racks and not specifying when the bowler takes them. Despite this, we rarely seeing league bowlers taking re-racks or even looking at the rack before bowling for that matter.

This was an interesting video and most of the time I was able to see the difference in ball path toward the 9 or 8 but there were a few times where the ball looked good and it was hard to tell as if was only off by a board one way or the other. It will take some practice to discern some of those close hits in real time at the bowling center.
I see the results of ball up and down adjustments, I'm interested to learn what other adjustments can change the trajectory by slight amounts and get you back on target. Thanks for posting this !

On the rack subject I rarely see anyone re-rack unless a pin is missing.

Many bowlers who target around the arrows never even look at the rack before rolling the ball. I had a teammate who once hit the sweep because he hadn't looked as far as the pins and therefore didn't see that the sweep had not gone back up.

While I do look at the rack as I'm setting up, at a distance of 70 feet, (length of my approach + distance from foul line to headpin), I'm not going to see that a pin is 1/4" off spot. If I were trying to earn a living as a professional bowler maybe I would be able to observe off spot pins.

This Is a great video. Re-Racking was mentioned. This is something I have not run across in either league I bowl in. Rob, have you seen or know what is allowed in the Red Rock league?

[RobLV1]

Re-racking is allowed in any USBC sanctioned league. I have re-racked in Red Rock leagues on many, many occasions.

[ChuckR]

Thanks Rob. This is a great video. I would think the many parts of a strike also come into play. Speed is one issue I have to concentrate on. Also finger and hand position will alter ball action. Last, but not least is the line I am using which results in the angle to the pocket. We have many bowlers that spend the night changing balls and not the other components that are an easier adjustment. If I am rolling comfortable for me, then I can look at the ball. In my case it is ball up. I only have the Mastermind Genius and UpRoar. If it is time to throw the Columbia WD for a strike, WOW.

I think it's a great video to remind people that where the ball leaves the pin deck off a pocket hit is generally going to tell you something.

Where I disagree with the video is obviously this was done by a bowling store that wants to sell Radical bowling balls. So every solution is a different ball. For 99.9% of bowlers that is ridiculous and useless. For pros, throwing Radical, very interesting...but they have ball reps to tell and explain this to them in real time so no need for the video. For everyone else, you should have a strategy for lateral movement, approach adjustments, loft adjustments, etc... based on these type of ball motions versus a ball up and ball down strategy.

For example...on a pocket shot with an above average delivery (that is VERY important because you never adjust off of a bad shot)...and you leave a 4-pin, 9-pin, or 4-9 split...that's an automatic move 1 and 1 left. No question, no debate, most automatic decision in lateral movements. Now, what happens after making that move and making another above average shot...that will determine whether you made the proper adjustment or if a further adjustment and/or ball change is necessary.

The harder adjustments to make are for shots hitting weak...because as the video "sort of" explained (by proposing balling up AND down); a weak hit can be caused by 7-25 different factors. For example;

You hit weak, it was a decent shot, it hit pocket, it left a 10-pin...looked like a flat 10. What could have went wrong?

1) Your release (axis tilt) could be slightly flat.
2) Your speed could be 0.2-1.5mph faster than the previous shot on that lane.
3) There could be lane/oil transition taking place.
4) Your ball could be too strong and "burning up" (losing energy) before hitting the pocket.
5) Your ball could be going slightly too long for the angle you're trying to play.
6) You might have missed by 0.5-3 boards right.
7) Your loft may need to be increased to delay the hook motion and/or get the ball further down the lane.
8) Your loft may need to be decreased because it's causing the ball to hook too early and lose energy.
9) Your release may have been flat due to multiple factors from not getting under the ball enough, to your fingers and thumb coming out simultaneously, to just not getting your fingers to "flip it" enough.
10) You might just need to move right because the pattern is too long or wide for the line you are trying to play.

So there's 10, off the top of my head. Any of those or any combination of those...will APPEAR to result in the exact same thing...a flat 10-pin. Obviously, these type of videos make the mistake of taking the vastly most important part of 10-pin bowling...which is probably at LEAST responsible for 70% of our success (approach/release) and make that a constant. They can then show how differently balls behave. Perfectly logical...but misleading to beginner and intermediate bowlers that have approach/release "issues".

[RobLV1]

Two things, Aslan:

1) Just because the people who made the video used Radical bowling balls does not mean that the knowledge is not applicable to everyone who understands the balls in their arsenals, just so long as the understanding is based on reality, not just their proconceptions (hint, hint).

2) Who ever told you that you never adjust off of a bad shot? That's nonsense! If you are bowling on a THS and you have the right ball in your hand, you can learn almost as much as if you throw a perfect shot. In many cases, if house bowlers wait to throw a perfect shot to adjust, they'd never move. Oh, wait a minute, many of them never move anyway!

So you're saying the "wait until the lanes come to you" theory rarely works ....

[bowl1820]

So you're saying the "wait until the lanes come to you" theory rarely works ....

Pretty much, if you wait until your making prefect shots or for the lanes to come around to make a adjustment. Then you most likely have waited too long, you've wasted so many frames you more than likely can't recover from it.

So you are better off making a change off a bad shot and seeing what happens, than wasting time waiting for a perfect shot or the lanes to change to base your decision on.

Note: I'm not saying anything about basing specific adjustments on a bad shot (or if you have the ball stick to your thumb and throw it through the ceiling).

Just that sometimes, if your not getting the results you want, You should just go ahead and make a change of some kind and see what happens. You only have 10 frames and that's not a lot of time to wait.

I have heard the saying many times over the years, I put it in the same category as 'waiting until the hot girl at the bar comes up to you"

I am way too impatient to wait for perfect shots to adjust, in fact if I am making perfect shots I don't adjust much at all !

I do sometimes find late in the 3rd game I end up playing roughly where I started !

I remember that thread.

If you were lost in the desert, would you wait for rain?

[Aslan]

If you were lost in the desert, would you wait for rain?

No. But realize if you're lost in the desert, you will probably die before you find your way out.

In this analogy, I'm waiting for night so I can see where the North star is and hoping like hell(o) I know which one is the North star and have some idea the quickest direction to travel to get me out of the desert.

Tony, on the other hand, spins a bottle and off he goes! Maybe I die in the desert and he makes it out. But there are a lot of dead bodies in the desert that thought they knew where they were going.

As Bowl1820 prepared for...because this horse has been beaten before...he specified that a shot stuck on your thumb that hits the ceiling you shouldn't adjust off of. Okay...so we got that down...that's a good start. Now think of the next worst scenario....

1) You drop the ball. Adjust? Switch balls? Yell at God for creating gravity?
2) You get excited and fire it 19mph into the 6-10. Adjust? Information? If you were wondering, "Geez....how would the lanes play if instead of bowling...I fired a projectile into the 6-10 pocket...mission accomplished!! :confused:
3) You throw 8mph, and just got a brand new Guru Mighty and it goes so far Brooklyn it misses the headpin. Info? Pretty blatent info there! You throw too slow to use that strong a ball on that line. Shouldn't have needed to throw it to figure that out unless it's the first shot at that house...ever.
4) You have a 200rpm suitcase release and are playing the same line as Jason Belmonte and can't figure out why it keeps going in the gutter. Keep playing that line and ball UP to something stronger? Pray for the "Gift"?
5) You have missed your target by 6 boards. Good luck adjusting off that.
6) You loft the ball so it lands 30ft out. Go ahead, switch balls. I suggest something lighter since you're going to be very tired by Game 3.
7) Your form is horrible, you nearly fall down, and are completely unbalanced. You hit your target by some miracle. Adjust off that? Maybe. Did the ball strike? I guess you're good then.
8) You fire 5 different balls up the 5-board playing a PBA pattern that you have heard PBA pros and USBC instructors tell you a stroker/tweener can't get outside of 10 due to out-of-bounds...are they full of poo? I got it...they are just worried that you're on the rise and gunning for their spot on the Tour so they're intentionally giving you bad information right?? Again...have the pro shop drill 10 more balls for you...because you're gonna be firing those suckers up the right side and missing badly...might have better luck at skeeball in the arcade.

Opinions vary (obviously) on the wisdom of making adjustments and/or ball changes off a bad shot. If I throw my spare ball at the 10-pin and I miss and it goes in the gutter at 40ft...I need to be determining why I missed my target and what I can do better the next time/attempt...not, "maybe I should use a strike ball....so it'll hook and stay in bounds!" :confused:

It's absurdity. It's like the occasional newb that comes in talking about how he bowls back-up style or intentionally tries to get Brooklyn strikes. The general consensus is that neither of those are good long-term strategies based on decades of bowling knowledge. But hey...Iceman bowled 2 perfect games and I'm 2-0 against MWhite in the ABHMAVZSCI...so I guess just do whatever; who cares?

[Doghouse Reilly]

Alright great examples!

Of how someone will try to discredit something they don't understand, by coming up with a bunch of over exaggerated scenarios.

[RobLV1]

Aslan: I've worked with you enough times to know that a great majority of the shots you throw are decent; not gross errors. If you're not perfect, you can still watch how the ball reacts and learn alot about miss room, if nothing else. I'm assuming that you are being facetious when referring to missing a ten pin with a plastic ball and thinking that you can somehow adjust your strike shot. If you choose to drink enough during bowling that your balance becomes impaired, then the ideas of ball motion and adjustments go out the window anyway.

[Amyers]

No. But realize if you're lost in the desert, you will probably die before you find your way out.

As usual with you lets take extreme examples and try to make a point with it. Does some of this stuff happen to us every now and then on one shot? Yes (some of it's just b.s. too) but if that's happening on a regular basis you suck enough that making adjustments is the last of your worries.

I generally am looking at about a three board area if it's in that area it's good enough. Waiting around for a shot to go over the exact board I want, with the release I want, and the angle I want I'll be there all day and never move. What difference does it make to wait if the next five I throw are going to be a board right or left of where I really wanted. Shots missed by 5 boards or more no probably not adjusting off that although I have found that I had way more miss room one way or the other that way before.

Part of the problem is your confidence and expectations. You don't believe in yourself so you assume the problem was you when I think often times it's not it's what your trying to do. We bowl differently but we are not too far from each other average wise but you seem to expect yourself to have a PBA caliber release. I don't I'm trying to improve mine doubt it ever gets that good but I haven't ever thrown a ball yet that didn't do what I wanted and thought man I screwed the axis rotation up on that one. Do I occasionally let of a stinker that goes straight every great now and again yes but I think you give way too much credence to your release and it's effect on where your ball ends up than you should.

[Aslan]

Alright great examples!

Of how someone will try to discredit something they don't understand, by coming up with a bunch of over exaggerated scenarios.
I could prove it. I could prove it on either league night. I'll just video tape the 4-5 shots from each team over the course of one game...and you can tell me how many of them make "good enough" shots to actually make an adjustment off those shots.


Aslan: I've worked with you enough times to know that a great majority of the shots you throw are decent; not gross errors.
You sure you're thinking about me?? ;)

Ding Ding Ding Ding!!

Amyers gets a gold star!! And that describes me as a bowler. I'm 'just' good enough to know how bad I am. Unless I'm hanging out at the alley on weekends trying to hustle kids at birthday parties...I'm to bad to make adjustments off my shots 2/3 of the time.


Part of the problem is your confidence and expectations.
Okay...again, ding ding ding....I think you're on to something...


You don't believe in yourself so you assume the problem was you when I think often times it's not it's what your trying to do.
Okay, that actually went in a different direction than I thought it would...but okay. Thanks!

I appreciate your and Rob's support, but much like dating...bowling and any other activity is all about expecations. I'd guess that at LEAST 90% of league bowlers are happier after bowling than they are before. They go, they have fun, sometimes they win 50/50, sometimes they have a good 200+ game, and they are glad to get out of the house and socialize.

10% CARE. 10% of bowlers range from the guy that is absolutely horrible but is really, really trying hard to get better and learns about the game and watches videos and tries to get better...but never goes that extra step of getting coaching. Then you have the guys that have just great natural ability and/or decades of bowling experience. They don't get lessons because they've thrown 12 300-games so they figure they're just a surgery or new ball away from the next level. Then you have the folks that are professionals...or at some stage of pro bowling success...whether a regional guy on the way up or a regional guy on the way down.

And finally, you have me...what I like to call, "The Dreamers". They study, they practice, they learn, they get coaching...but they just don't have "it". Iceman called I the Gift. And honestly, I thought at the time...like most times...that he was full of poo....and he still is on most every topic. But maybe he was right about the "Gift".

Could I be a solid #3 or #4 bowler on a league team that kinda thinks they have a shot at finishing in 1st place in some loser handicap league?? Could I be one of the better no-tap bowlers in some weeknight pizza league? Sure. But enter..."expectations". And that's where everything falls apart. I'm a 170s bowler. I can dazzle folks all day with fancy talk and analysis...I can point to my improvement over just over 2 years...I can impress casual bowlers...I can even win brackets half the time. I'm even good enough to give some helpful advice from time to time. But I am woefully lacking in skill to compete at the level I someday hope to compete at. And that "dream" is only possible if I can start taking some real steps forward. I have short, intermediate, and long-term goals...but if I can't even hit the short-term ones...the others don't matter.

Compare me to John Burkett. He started late (post-baseball), learned a lot, had the will to succeed and was humble enough to be able to learn...yet he's one of the top PBA50 bowlers and I'm not even good enough to join an amateur tournament or even be on a decent scratch team. Gift? Maybe.

My approach is very, very fair. I expect to make a perfect shot every time. I know I won't...but if I want to meet some of my expectations...that's what I need to do. Not 1/3 of the time. Not "only when it matters". Every shot, every frame. I am FAIR to my arsenal in that way. I'm never going to blame a ball if I can't make it work....because I know high level bowlers can bowl with a house ball and easily roll a 630 series on a THS. BUT....if I make a perfect shot (or close)...and it doesn't carry...then it's the ball or the line. But I won't criticize the ball if I can't execute. Execution is on me.

People want to "bowl for fun"...more power to em. Go bowl a 420 series and if you have fun...I'm all for it. I love the game. But a sub-500 series on a THS from a bowler with my intellect, my lack of any serious physical constraints, and with the coaching I've been blessed to have received? Unacceptable and NOT FUN.

Found this on YouTube and I thought it was interesting. From what I can tell balling up means an earlier rolling ball and balling down is a later rolling. I wanted to see what some of the more experienced guys thought of this video.




If you watch this video closely, you will notice with one exception, every time the exits over the 8 pin, if had first hit the head pin higher than the "pocket", and likewise, when it exits over the 9 pin, it had hit the head pin lighter than the "pocket".

The cause for the 4 pin, is where you hit the head pin.

The cause for the 10 pin, is both where you hit the head pin, and if you happen to hit the pocket correctly, the amount of deflection.

The video doesn't include an example of hitting light, and exiting over the 8, or hitting high and exiting over the 9.

If instead of saying where the ball exits, but instead where the ball enters, you will see their advice on switching balls doesn't make sense.

If you hit high:

Using a strong ball, use a weaker one.
Using a weak ball, use a stronger one.

If you hit light:

Using a strong ball, use a weaker one.
Using a weak ball, use a stronger one.


Hitting high vs hitting light are opposite problems.

How can the "adjustment" be the same in both cases??????



Here is an example of some shots where the ball hit the pocket, but with enough deflection to exit over the 9 pin, yet still carry strikes.

If exiting over the 9 pin caused 10 pins, then this video shouldn't exist.

While you're waiting for the night, and hoping to figure out which is the North star, don't you think it would be a good idea to see where the sun sets.


In the deserts around me, it sets in the west.

Well, the "3 Wise Men" used the North star to find baby Jesus....and they were "wise"...so I'm just trying to emulate them.

But yes, in a way, you're talking about exactly what I was struggling with.

"Hit light, move right. Hit left, move left. If it hits the pocket and leaves a 10-pin or 8-pin, or 7-pin, you need a stronger ball or to lay the ball down earlier. If it leaves a 4-pin or 9-pin, you need a weaker ball or to move 1:1 left."

What I quoted, is sort of the "general rules" for adjustments that we all learn when we first start out. The problem I was having with those rules is...they don't take into account when a ball is hitting weak because it is losing energy. If you have a ball with a lot of surface and/or a lower RG...it MAY be...that going to a stronger ball (after hitting 'weak') will cause you to hit even weaker.

And that's where the old rules kinda wash away. And that's where I get so confused in arsenal selection, etc... Too many specs are working against each other.

I took a class in Astronomy years ago (back when Haley's comet came by) and in one of the presentations was a comment about the star the "3 Wise Men" supposedly followed.

If they used that star to get where they claimed to have gotten, it would have had to have taken place in June or July, not December.

You really need to get the "ball losing energy" concept out of your thinking.

In the world of physics, thats not how things work.

If you go out on a bone dry lane, the ball will change direction, and it will maintain that direction all the way down the lane.

Lets assume you put enough into the ball to achieve 2 degrees of entry angle.

But it completes the hook phase too soon, you're going to cross over the head pin, but still have that 2 degrees.

Now you try to adjust by throwing the ball left to right.

Lets assume you release the ball at a negative 2 degree launch angle, you only put enough enough in the ball to achieve 2 degrees, those 2 degrees are only enough to get the ball rolling straight down the lane, so you end up with a 0 degree entry angle.

Now lets go back and oil the lane.

Assuming you play up against the oil line, between the mid lane, and the end of the pattern, the little bit of friction your ball sees will cause the ball to hook (converting energy to momentum) but once the ball hits the heavier oil, it loses momentum like a car trying to coast up hill. It can't climb to the top of the oil so it slides back to the right were it finds friction again. convert again, lose momentum again..

If all of what you put into the ball is converted to momentum, and the oil killed all of the momentum, that ball rolls straight off the end of the pattern.

If you pitch the ball out earlier (negative launch angle) and the ball generates enough momentum before coming back to the oil, it can actually climb the wall of oil, and you're likely to cross over.

If it doesn't have enough momentum, again the oil will kill whatever momentum it had.

If you didn't put enough into the ball to get back to the oil, you have to first overcome the negative launch angle just to the get ball going straight, then hopefully have a bit more to generate positive entry angle.

Now the ball is going into the roll phase earlier, and from wider right.

You better had put just the right amount into the ball otherwise you're not likely to hit the pocket,
