I was first told about this rule at a IAB boot camp. Recently, I watched a Kegel video on YouTube that talked about it and explained it. But there was a part that confused me, which was a reference about adding 7 boards based on your fishing slide foot.
Can someone explain this to me please. Lets use a 41 foot pattern, so minus 31 we are at 10. How do I apply the 7 board info I heard in the video?
Thanks

For the typical bowler, the center of the ball at release is 7 boards from the slide foot. So if you want to play straight up 10, your slide foot would need to end on 17. If you are not playing straight up the boards, you have to adjust so that the ball is at the desired point at the end of the pattern (in this example the 10 board at 41 feet).
-
I understand it but not sure I can properly explain it, but here goes.
Let's say you want to play straight up the ten board on that 41 minus 31 pattern. The laydown point of the ball will have to be the ten board. The average man's width is about 7-8 boards, so that means that the sliding foot will be that far from the laydown point. Assuming RH bowler, that means to lay the ball down on the ten board, the sliding foot will be about 7-8 boards left of that, or on the 17-18 board.
Don't forget that if you are factoring in where to stand on the approach, you have to take into account your drift factor. I don't drift, so mine is zero. I think if you drift two boards right, then you have to add 2 to the 7-8, so your starting point on the approach would be on the 19-20 board in order to end up at the 17-18 board so that the ball laydown will be on the ten board. If you drift left, subtract that number.
If I am incorrect on this, someone here will correct me.

You stated it exactly as I understand it MI 2 AZ.

Just an an FYI....Mo Pinel doesn't agree with the rule because of the pattern reverse oil that is applied. I'll have to find the post don't have time tonight.

Great post Scott, I also use Mo's breakpoint system if the pattern breakdown is available. Both systems are useful, I've just had more success with his.
-
Scott, Mo corrects himself later in that topic. It is forward oil, not reverse that determines the breakpoint. Below taken from two later posts:
______________________________
My bad! It's the red bar (the forward oil) that I meant to refer to. The forward oil controls the breakpoint location. I'm getting either senile or color blind.
Look for the highest corners of the red bars on the bar graph and subtract 3. That's the place to start with the breakpoint. Remember that the loads are applied to the buffer brush, so ALL the forward loads affect the breakpoint.
-
Correct Gary I forgot about my post last night and to correct it.. It is still not the 31 rule though.
Also, if you really want to understand the more technical aspects of bowling BC.net is head above any other site. There are other topics on that site that refer to why 31 is just a starting point and other lane conditioning situations with ball reaction.

The "Science of Bowling" per Dick Ritger tapes relates to the slide foot position, drift etc. so very important!
The rule of 31 = pattern play ie a 43 foot shot is usually played well by hitting board 12 at the breakpoint. 43-31 = 12. Very important also!
Two different rules one that relates to becoming a very good form bowler on all conditions house and sport. Another rule relates to lane play the rule of 31.

PS I was lucky enough to get to practice for awhile with the great Dave Davis. Some days no or few strikes for 45 minutes of practice other days almost all strikes for his opening 45 minutes of practice. People would say "Dave, almost all strikes" on his good days,
He'd reply, "I didn't notice"! He was practicing the science of bowling to open all practice sessions, focusing on closeness to ankle, slide foot position, and slide board! What form! and from what I heard, what form under pressure!

Rule of 31 relates to the exit point from the pattern, not the breakpoint. 2 totally different things. Trust me, I've been corrected on this myself.
-
Yes, you are right!
I look to the end of the pattern and put it in words wrong!!

What is the difference between the exit point and the breakpoint? As I understand it the exit point is just where the oil ends on the lane. The breakpoint is the point where the ball starts it's hook. I guess I am a little confused. I have been told using the 31' rule that that is where I want my ball at when leaving the pattern (exp 41-31=10 board), would that also be where my break point is also. Or if swinging the ball would I want to exit the pattern at 10 using example above but my breakpoint may be at 5 board.
-
mrfrostee, the breakpoint can happen before or after the exit point from the oil pattern.
For example, a high volume shorter pattern can have the ball skid much further than the exit point from the pattern and an extremely low volume longer pattern can have the ball break prior to the end of the pattern.
This youtube video from 4:30 to about 5:00 minute mark is the best way to physically show the difference between exit point and break point: http://www.youtube.com/watch?v=w62JZe_rBmk

Lookingforaleftywall, thanks the video helped tremendously.
When the lanes start to transition, would I look to move my exit point, my breakpoint or both?
-
These targeting systems really, really help on tougher patterns. As we all know, most house shots allow us to just chuck the ball to an area and still stay in and around the pocket. However, if you've bowled on Sport or watched others do so, you've probably realized just how important it is to use these methods. Sadly, you still have to be able to actually hit what you're targeting, so that's why I'm SOL! I suck.

Your feet to answer you question. You want to chase the oil in and slow your speed to allow the ball to read.

Correct Gene. In my world...just find friction on house shots and work from there. I don't even worry about a so called 31 rule on house shots. Much ado about nothing.
-
Funny, it does seem to be close to working even on house shots! (the 31 rule of course!)
