What's the difference between board coverage and hook?

[bowl1820]

Ok. Thanks for clarifying that. I'm getting it!

Now: let me deviate a bit and throw up a shameless argument.
Looking at the illustrations, we see the black path describing a continuous curve from beginning to end. Since it is such -- or at least appears to me to be such -- what part of that continuous curve represents the "original trajectory" sine the path never deviates outside it's curve? From the moment the ball is laid down, it's all "hook," yes? the red path is obvious, the green path a little less so, but still discernible. Or is the black path not as continuous a curve in reality as it's shown in the illustrations? is there always a point where the ball is traveling a straight trajectory?

The illustration is not remotely to scale and so the ball paths are slightly distorted and would look different on a actual lane. It's was just meant to illustrate the idea of the boards being covered by the ball. Not actual lane play.

The "original trajectory" would be the angle from the laydown point to the breakpoint.

So the picture isn't an accurate representation of what some balls do. No ball makes an arc move from the get-go.

You might as well just grab your magic 8 ball in ask it how many boards your ball hooked.

Lets take tour first example.

You stand 31, and target 16.

Okay

While you're standing on the approach, your foot is on 31, but the center of the ball is more like above the 24 board.

Not really...more like above the 21 board...but it's dependent on the width of your shoulders and where you hold it. Continue...

Now you walk towards the target and release the ball. At the point of release your ball should be above the 20 board.

Nope. Still 21...assuming we walk straight on a strike shot. You'd walk towards your target pin on a spare shot...but...okay...still 21.

In the first 15 feet your ball has moved to the right 4 boards.

If I'm aiming at 16...standing 33...ball 10 boards right of my left foot at 23...first of all.... I'm laying it down at about 18-20 depending on the loft...so...okay...20...continue...

Thats (20-16) = 4 + (33-20) = 13 So thats 4 + 13 = 17 On a standard fresh oil shot....that resulting number is about 10. So we're talking an AGGRESSIVE line on some dry arse lanes!! But okay...I lay the ball down...

If your ball hooks 0 boards, it will be on the 4 board at 60 feet.

Actually...sooner than that. With that line...I'd imagine it would be at the 3-board or in the gutter at 60ft.

If you hit the pocket, your ball has "hooked" about 13 boards.

35 approach 19 arrows to pocket would result in 17-((19-(35-7+19)/2)*3+19) = 11.5 boards of hook.

I don't think I've ever seen you release a ball that hooked 5 boards, so 13 is a big stretch.

Well...

A) You're doing it wrong. The overall boards "hooked" that I calculate is based on starting position and target...not how far the ball hooks once it starts it's "hook phase". My system was designed to give you a Benchmark ball and a progression up and down. Therefore...you couldn't roll every ball on all 3 lines and measure the boards and hook phase and roll phase...not in 15 minutes of practice.

B) In THAT scenario...the ball enters the hook phase WELL before the 3-board at 60ft. That ball is traveling just shy of 15mph (not 19mph)...and it would generally begin it's hook phase at 45ft on fresh oil...probably 40ft "ish" on drier conditions. So we're talking more like the "7-board" at "40" ft??

So using your system...it actually hooks from the 7 to the pocket over the course of the last 20ft...so thats about 10 boards from hook phase to pocket on very dry conditions.

And no, you won't see that very often because other than the wood lanes we bowled on...THAT dry of a condition would be impossible for YOU to bowl on.

For reference...at the tournament Sunday...I was standing 20.5 and aiming 6.5. That puts the ball at 6.5 on laydown...straight up that board...so it's easier to calculate the hook into the pocket (which I hit a LOT) of 10.5 boards. So you must have been distracted by something shiny on Sunday or you would have seen my ball hook 10.5 boards a LOT!!

To give you an idea how wrong this concept is...

Lets take my shot at a 10 pin.

I start with my feet at 33, and hit the arrows at 17.

I lay the ball down at 21, and it slides all the way out to 3 board when it contacts the 10 pin.

It goes out 18 boards, and comes back 0 boards.

Therefore the ball covered 18 boards.

It would be a big stretch to call any of those boards a "hook"

Again....you wouldn't calculate "overall hook" on a spare shot where you're trying to throw it straight. I stand with my left foot on 33 and my target at 17 as well...and my only hope is that I have my shoulders aligned properly.

If you watched my recent (awesome) Encounter project (link to my youtube videos by clicking on my USBC number in my signature)...I'm sure a trained expert like yourself...will CLEARLY see...in slow motion no less...a ball that goes up the 11-board....maybe out to the 10-board...maybe 9...and it hooks back to the pocket. Thats 7-8 boards right THERE...using your system...so you've SEEN more than 5-boards out of me....you just generally aren't paying attention. And why would you? I wouldn't pay attention to me bowling either!

So the picture isn't an accurate representation of what some balls do.

Yes it's was just a rough approximation to illustrate a point about boards covered not ball paths.

No ball makes an arc move from the get-go.

You know what? I don't know. I'm not saying it can or can't.

Just that it was quick sketch using a small not to scale diagram, to show a basic idea about something.


Just to throw in, here is a slightly more to scale diagram I found (it even has a oil pattern). with the same black and red lines.

Oh! Did you make those diagrams? Cool!

So, in a nutshell, I'm doing my typical overthinking-without-having-all-the-information thing again.
