Does anyone think pocketing comes into play? I've always felt it does but never gave it much thought. In other words when the ball hits the strings the varying degrees of face closure will affect how the ball pockets into the strings and this would have an effect on the spin produced.

It seems that most of the formulas and calculators are using hard collision theory like billiard balls but I would think that what's happening is more of an elastic collision. Like since the strings bend and push back there might be some effect of different tensions on the string at different points of the ball thus affecting spin somehow... Or something... idk.

and maybe a racquet flexes differently depending on how you meet the ball etc etc.
