Eric,

I always follow along when you do a recommendation to see if I "get it".

I get the 100-degree sweet-spot from his speed and rev rate.

I believe the angle ratio of 1:1 is chosen (because of his high A/T and A/R) to get the ball to reach 1st transition sooner as well as eliminate any jumpy back-end reactions.

The "longer" ASYM P2P distance is to help burn off A/R and A/T quicker (because he is a Tweener)?

Inquiring minds want to know! (LOL)

PAP = 4.375 over & .75 up (flaring)
PAP = 5 over & 1 up (non-flaring)

The Ratio is take from the Dual Angle Ratio Guide mainly based on his tilt.
Yes to your description about getting the ball started sooner and have a smoother hook.

Again the tilt is the major component in choosing the Pin to PAP distance. Longer pin to PAP's for higher tilt bowlers.

Comments in color above
