How to Find Your Stats | Rev Rate, Ball Speed, Axis Rotation, Axis Tilt

[@traviskirk3834]

I am 60-65 axis rotation, 10 degrees tilt so low tilt , I am speed dominant lefty , low to average rev rate, while pap is 4-9/16

Since the Armadillo ribs are marked in inches, I usually just use the the ribs to measure the distance from the PAP to the first oil line, subtract that distance from 13.5 (distance from PAP to NAP), then divide by 2 to get the arc distance across the NAP. ie: 8" distance from PAP to first oil line; 13.5 - 8 = 5.5"; 5.5 x 2 = 11" arc distance across the NAP.

Mark, help me understand drawing the line around the ball please. With all the flair rings, how do you choose which line to draw on?

[@spectrebowling]

Take the one closest to the fingers and thumb. Follow that one all the way around to measure the tilt. If you place the ball track parallel to the counter top it will give you a good visual to if you drew the line correctly.

So please, how does one get out of bowling a full roller. Harder done than said I guess.....

[@spectrebowling]

Most of the time it's because you're turning the hand too early. I try to tell people to point their thumb to the ceiling at the top of the back swing, this will allow them to rotate the ball at release. If your hand is already on the side of the ball at release, the only way you can turn is the "opposite" direction, this is what causes the full-roll. A good at home exercise is to throw an american football underhand with a spiral, do a bit of pitch-and-catch with a friend and this will hopefully help your release.

@@spectrebowling thanks, I'll try what you said and hopefully it all works out. Thanks again.
