Very nice and in principle I like what you're trying to do.
But what some players have available are very tight, very finicky, 9' Diamonds, or even GCs set up to very tight specs. Given that type of equipment, why would someone try and compete against another player shooting on a table with far more forgiving pockets. As you would know, how much wiggle room you have on the pockets makes difference, not only pocketing the balls, but playing position.
I don't think it can ever be a fair, universal test.

Goddammmmn aint that a pool player thing to do? Complain about a free roll and make excuses before they hit a ball... Not that you'll actually give this a try.
Here's a thought, go to a different table...
