For instance:
15 MPH / X revolutions
Has anyone every read anything that talked about this?
If so what was the book or site if you remember?
What got me wondering was I watched took video of a few different bowlers
with different styles and they all had about the same ratio.
stroker 16 MPH / 4.5 rev, ratio 3.55:1
tweener/power stroker 18 MPH / 5.25 rev, ratio 3.43:1
cranker 21 MPH / 6.25 rev, ratio 3.36:1
the above speed were all calculated in time at arrows 15 ft
T * 4 / 40.91
rev rates are the amount of revolutions by the arrows
5 shots each bowler then averaged to the nearest 1/4
by the way I have a 3.43:1 15.3mph 4.45rev ave for 10 shots
I think that this ratio could be very useful when selecting
a ball if there was an actual study done on it to where a
scale could be made from the findings.
What do you think?
Edit due to a point Lucky made
Revs to pin deck assuming no roll out
Stroker - 18 revs, ratio 1.125:1
Tweener - 21 revs, ratio 1.167:1
Cranker - 25 revs, ratio 1.19:1
Me - 17.8 revs, ratio 1.163:1

I think one to one is pretty good using this method. But sometimes a little strong for today's conditions. Particularly if one has a lot of axis rotation.
The best bowlere on today's conditions I believe are below 1 to 1 revs to speed and have a little less than 45 degrees of axis rotation. This allows them to play a lot of different lane conditions in somewhat similar ways and have less variance in placement and dramatically different reactions due to lane conditions.
Slower speed players with a lot of revs, 1.3 to 1 revs to speed with a lot of axis rotation can really get it going but struggle adjusting. How do I know.
I are one!

The reason I say this is if you do the math:
Ball 2.25' in circumference
Lane 60' in length
60/2.25=26.67
So the total revolutions from foul line to pin deck will
vary quit a bit depending on when the ball rolls.

okay, if your so smart, calculate a 17 MPH bowler, because, um.... i want to make sure you can do it right
6.25 / 15 ft or
25 / 60 ft = 1:1
40.91/17=T
60/T=R in 60'
R/4=R in 15'
