So I did end up having time to read through all the pages, and boy, did that turn into an argumentative mess real quick.
There were a lot of valid opinions on both sides... but I'd say a lot more off-topic than anything else. There's great stuff in here about feeling stroke, lessons, etc. But the closest to the point was Scotty and Randy's system.
The idea being that if I needed to write down on a piece of paper how to hit a particular shot and hand it to someone (or a computer) to shoot, it'd be fairly accurate assuming we were speaking the same language on stroke speed. (lag system, diamond system, Scott+Randy, etc)
So.. the point of my original question was figuring out a good common ground language for speed, regardless of whether not both parties have to learn it first.
But anyway, all input is good. And as with any good discussion, it's bound to get heated from time to time.
If you wrote a number down on a piece of paper & handed it to every player in Buffaloes Pool Hall on a crowded night other than some APA league night, I doubt that any player in the hall except maybe JoeyA would know what speed you would want the ball hit.
Just food for thought.
