Aslan's Weekly/Monthly Chris Barnes/Joe Slowinski Statistics Nerd Thread: Part I

[vdubtx]

One statistic that I think is interesting and I am sure you will touch on in one of your later posts is which pins are left the most and why. Could even dive deeper and find which ball that you used, left you the most 10 pins for instance.

For me 4 different pin leaves are left the most and account for 46% of my leaves. 10 pin #1, 4 pin #2, 9 pin #3, and 7 pin #4.

1) Does that graph tell you ANYTHING? If so, what do you see?

Since the data points can represent anywhere from 1 game to a dozen, I don't find them very useful. The fact that the line is essentially level and the bulk of the data points are close to it, shows that, whatever improvements you've made to your game, they haven't affected your first ball pin carry. My conclusion would be that you are still missing the pocket more than you might like or that you're hitting it at the optimal angle and phase of ball motion.

2) Is that STAT really that useful?

Don't ask me. The only thing useful that I learned in Statistics was that you define what success is. All this Stat tells me is that you still have a ways to go before challenging Belmo for domination of the Bowling World.

Agreed J Anderson. Missing the pocket and only getting a 7-8.5 first ball average to me means the pocket is not being found. Likely need to work on targeting on the lanes until you can get into the 8.5-9 range.

Kudos to JAnderson for actually answering the question as designed!!

I agree VDub. The only thing I can get from that STAT and that set of data points is that if the trendline is flat and about 8.40...

1) There has been no progress nor decline in terms of carrying more pins with the first ball over the course of 2014.

2) A # lower than 8.5 would indicate that you're not only not striking enough, but also leaving far too many multi-pin spares versus single-pin spares.

While both of those are interesting...this STAT doesn't really shed any light on "why" or "how" and thus isn't that useful in terms of fixing the problem. But it is useful in seeing that there IS a problem. And it is somewhat useful given the lack of a trend (positive nor negative) which shows that the changes in the person's game over the course of the year have had very little effect on the particular issue of pin carry.

Of matter of fact...THAT is the most interesting take-away from this set of data. This is a bowler with 0.5 years experience and in .75 years of data...there is no improvement (judging purely by this stat). New bowlers generally will show a much greater level of improvement early on because early, simple, fundamental types of changes tend to lead to huge gains. Once you get to a higher level (175-200 average), suddenly changes produge much less results in terms of pin carry because you're already at a very high level.

Another difficulty with this STAT/DATA SET is it's hard to tell if the R2 value is good or bad. You'd need to compare it to a similar bowler (in terms of average) to see if THIS data set is more or less scattered than it should be. It looked a LOT less scattered when the Y axis was 0-10 versus when I changed it to 5-10.

Lets try an experiment this Sunday.

Lets remove from your game the one factor that it probably doing you the most harm.

I'll tell you where to stand, and what target to hit. I'll decide when you should change lines.

Your whole job will be to hit your mark.

I think it is your though process that is giving you the most problems.

Come down early enough to get a game of practice in before league.

Excellent. Practicing hitting the mark is great. Get all things out of your head but to hit the mark and not worry about(yet) where the ball is ending up after hitting it. Did exactly this several years ago, and also this past summer with Susie Minshew. She only wanted to see how accurate I was and how repeatable I was with my shot, not if I was hitting pocket each and every time.

You also need to have confidence when you bowl, if youdont you will not bowl good
. You need to clear your mind and just concentrate on hiting your mark, and getting good lift on the ball and your scores will increase

Ooooo...an "experiement"! I like those!! Sounds like a plan!

Actually hitting the mark isn't going to the problem. I don't want to spoil the results of the exeriment prematurely...but I can usually hit my mark within +/- a board. The problem is more in the release, the timing, and how square I am to the foul line.

It's one of the issues I've been having with the new plastic ball spare shooting system. The coach gave me exactly where to stand and what mark to hit...and I'd stand there...and hit that mark...and the ball would miss. And the reason I was told was I was squaring up to the foul line rather than the target. So I'd be all lined up and that at the last moment twist my torso and aim more towards the headpin rather than the pin I'm trying to pick up. To "correct" this I've been instructed to line up aiming a little left of the target...so when I have that tendency to square up...it still goes towards the pin. Granted, when I concentrate on NOT squaring up...I then miss left (7-pin) or right (10-pin).

Usually if I miss right of my mark, it's because I'm not square with the foul line. I'm "pointed" right...and it's just bad timing. I also will sometimes miss right if I put too much speed on the ball. I miss left if my timing is off (I can't remember what is late vs early). But if I'm at the foul line and the ball is still up high in my backswing I'll tend to pull the shot trying to "hurry/pull" the ball down.

And I'm also less accurate if I'm straight up and down vs. bent over/forward tilt. My old lofting style I had trouble hitting +/- 2 boards because the target was simply further away from where I was releasing the ball. I then started leaning over the foul line almost TOO much and could hit the board/target every time...but the release was too flat...the ball going to slow, no revs, and hit the pocket like a marshmellow.

But we'll see. I can't do any worse than usual. Wait...I guess I could. But thats alright. I just won't do the brackets and sidepots this week.

Mike is right though, you have too much going through your mind to try and get right to get the shot to go where you want. Your body is likely wanting to get muscle memory, but you're not letting your brain do that for you. Just put things out of your mind and just do it. Don't think during your approach that you body has to be square, you have to release it just so etc. Just think of that in your stance, get into your approach and let your body(muscle memory) take over. Believe me, I was in the same boat as you are years ago and I was told to stop thinking so much and just do.

You can blind fold someone to make them stop using their eyes.

I wonder if there is such a thing as brain fold.

Probably would require strong drugs, and likely illegal.
