ball wear and weight effects
Enjoy,

Yes. The index is called the "coefficient of restitution" (COR).Also, the other things i wanted to ask are, do you have some sort of index for the elasticity of the polymer used in the billiard balls? Their bounciness?
I don't have data comparing the CORs of different brands of balls; however, the following resource page explains and illustrates what effects different CORs have on different types of shots:The elasticity of centennials, vs aramith pros, vs the "pea" balls, or even ivory balls and how those materials transfer energy and bounce off of each other?
FYI, wear, size, and weight effects are covered in detail (including video demonstrations) here:Maybe info on some other factors such as switching out the cueball that comes with the set that is the same weight, and replacing it with a lighter ball, and how that affects shots?
Cause it could be that some of the phenomena observed by pool players all over the world, is a result of something simple, like cueball wear, and the subsequent loss of cueball weight when striking an object ball that is not out of round, and heavier.
Enjoy,
