Ran across these bowling terms in Physicists’ language.
Mass distribution
Pin = Weight block symmetry axis—intersection with ball surface.
Labe/CG = Center-of-mass offset axis before drilling—intersection
with ball surface.
Pin in (out) = Center-of-mass axis before drilling and weight block
symmetry axis form an angle of 25° or less (or more).
(25° is around 1 7/8" pin to cg)
