What exact dual angle sum adaption to unmatched players ?

Post by PlainUgly »

Hello everybody !

How do i adapt angle sum to different player types exactly ?

At medium Axis Rotation ( 35-55*) with medium Tilt ( 13-20° ) its 95° basic sum for benchmark layout

15 mph matched to 200 rpm
16 mph matched to 250 rpm
17 mph matched to 300 rpm
18 mph matched to 350 rpm
19 mph matched to 400 rpm

What amount in degrees to subtract for a player who has not as much revs to be matched....

17 mph with 250 rpm ...... minus 10° ?
17 mph with 200 rpm ...... minus 20° ?
17 mph with 150 rpm ...... minus 30° ?

..so for each 50 rpm less minus 10° ??


What about High Tilt ? only minus 10° for > 24°
What at 40° ?

What about High Rotation ? only minus 5° for > 60°
What at 90° ?

For the basic speed to rev relationship I utilize a spreadsheet that one of our members, Libra, put together by compiling recommendations from Mo.

It can be found here...

viewtopic.php?f=6&t=8770&p=69777&hilit= ... les#p69777" onclick="window.open(this.href);return false;

Once you get the speed and revs basic total I then adjust for tilt and rotation if needed.
Add 10* for low tilt <12* or subtract 10* for high tilt >20*

For rotation I subtract 5 for high rotation >60* or add 5* for low rotation <35*

And that's it I don't adjust further.

Thank you Eric, that's the missing link I needed in order to do layouts correctly! I feel like Keanu Reeves in The Matrix: "I know kung fu"

" onclick="window.open(this.href);return false;

Boy I sure miss Mo around here, could someone here tell him to post a thread to just say "Hi, I am proud of you guys" or even better "you guys suck, I'll post a bit more often to show you some new stuff"...

Hello Mo, wherever you are, thank you for all you have contributed to this forum, we try to keep it as accurate as possible.

When I helped him at a seminar last month I asked about his absence.
Hes very limited on time, once time permits he will post again.
Its nothing anti-BowlingChat, just time constraints.

Thats a nice little tool !

According to that, its a linear adaption of 5° each 100rpm or 2 mph variance

But one has to be careful, thats not for everybody. I wont believe having 11 mph and 0 rpm results in the same basic 95° angle sum as 17mph / 300rpm. Even if this is true, thats not a question of layout, thats about learning to bowl.

For myself it should be enough to work with 5 ° a the smallest unit. When i look at the area of 5° difference at a ball thinking about the variance of bowlers PAP coordinates at release, it will be just fine i think. Once a top bowler with stable PAP release should ask me for help, i will remember to calculate more accurate and dont round the sum.
