A number of factors working here.  First you need great ball fit to change any factor.  No knuckling.  For the majority of us I'd say it's pretty difficult to change tilt and much easier to change axis rotation.  You can have low tilt and a major amount of of axis rotation and hit carry from inside.  Pete Weber would be the best example low tilt and 90* of AR. 

Clear thumb earlier for many will cause tilt to go up and drop the vertical component of your PAP....make it go down towards the mid line.  I am 17* of tilt and 4 7/8" over and 3/8" up.  I can go down to 5" over and 0.  Very close anyway and hard to change much more than that.

After looking at some videos (Don't have a very big library, only a few bowlers). It would seem that a bowler would be using the side (or corner) of their fingers to put revs on the ball to get the tilt down.

Take the extreme example. Spinner Release (Very Low Tilt). They are clearly not revving the ball with the pads of their fingers, instead they come around the ball.

Another example. I know some bowlers who use grips and they are constantly wearing out the side of their finger grips. Obviously these bowlers are using the side of their fingers to get revs which probably drops their tilt.

This is up for debate. Just throwing my ideas out there.

In a general sense it's the higher you track the ball or more the track diameter the less tilt you will have.  A full roller or high track style would have little axis tilt.  Spinners will have the most axis tilt. 

BTW...it's the two elements put together axis tilt and axis rotation that correlate to ball motion, layouts for best performance, etc.  Spinners would have high tilt but low axis rotation.  PDW has low tilt but can make the ball hit like a truck on the back end because of his high 90* axis rotation as an example. 

Good illustration on releases on Ron Clifton's site.  http://www.bowl4fun.com/ron/tip35.htm

That style (PDW) of release doesn't do well on light to dry conditions.

Scott, I wanted to state earlier, changing tilt from 0 to 17 is very interesting. That is quite a  jump.

His tilt is not changing from 0 to 17.  The tilt may not be changing at all.  His axis coordinates changed slightly.  They are not an accurate measurement of tilt.

Okay. I see it. I was discussing about changing tilt. I made the assumption. LOL!

It's not that simple and most people can't change their tilt very much and very few actually are successful at using it as an adjustment. 

"Of all the video footage I have. I usually only see PAPs in the lower numbers of tilt. So had me wondering could that PAP be in other places. On that grid."


Sorry, my decoder ring is not working at the moment.
