Claudio,
The last thing I heard was that Storm has not officially released the chart. I don't know that is still true today.

I may be wrong but isn’t the “lightning arc” the hypotenuse of a right angle triangle: horizontal coordinate and vertical coordinate being A and B sides of the triangle? If that is so then the square root of the sum of the squares of A and B will give you “lightning arc”. Someone more skilled than me please verify.

Hey, Tony

You might be on to something here, but you would need to solve for the hypotenuse of a spherical triangle, I believe.

I was able to use an axis revering tool to bypass the need for the Lightning Arc and fifth VAL arc.
I also tested this with a normal quarter scale and Spyder tool, and both worked fine.

This brings into question, in my twisted mind, the methods used to measure the PAP. Why not just measure the distance from the cog to PAP, then measure the angle of the PAP to the vertical grip line, since both of these values would be static constants for a given bowler.
ie: 5.125" x 75 degrees.
