Sounds like you've got it all figured out.With my system, as long as I don't shoot too hard or too soft (or extreme english or throw from really dirty balls) the cue ball hits the exact spot on the object ball that I've chosen to hit and I make the ball. But I figured out quickly that simply shooting really hard throws everything off. I don't care what system you are using to aim, if you fire a ball in, you're going to miss if you aim at the object ball the same way that you do if you shoot soft. Throw from dirty balls and extreme english have similar effects that you need to compensate for and aim at a different spot. Because that's the case, CTE as well as my own system gets you "close", but you still need to make changes on the fly if you shoot really hard or soft, or you're going to miss. I can't make my point more clearly than that. If you don't agree, that's fine.
Enjoy yourself.
