So how many shots or angles could a true pivot system be used for? Talking no adjustments or anything, strictly follow the instructions. You say a few shots, what are they?
I think PJ or someone worked out some numbers. I say it depends on on the table - length and tightness of pockets. Rough stab I'd guess you might make half the shots with a "professional" CTE system if you didn't tweak the alignment to the (already known) shot line.
Maybe I missed it so I'll ask. Do you dispute Brian's comment (and why), which was:
Now, looking at pivot aiming, it's equally as absurd to think one or two pivots can make every shot simply because they happen to work on a few shots when the balls are in the right position. On every other shot, when the balls aren't lying perfect for the pivot, the player must develop the ability to either tweak the offset or tweak the pivot point in order to arrive on the shot line, and they must be able to recognize that they are on the shot line.
