But delivering the CB to a precise location is only half the battle. Accurately hitting the CB to apply the precise amount of spin comes into play as well. Am I just over-estimating the amount of precision needed? Is that something that takes care of itself with a repeatable stroke?
That's my position. It's fairly controversial, but I think it's really easy to overthink addressing the cueball, with disasterous effects. There are so many micro things going on; your stroke mechanics get fine tuned over time, in ways you really can't control consciously. Muscle memory over time doing what works and avoiding what doesn't is what gets the proper address on the cue ball. You can hit the cue ball perfectly where and how you want, but it's irrelevant if the cue ball doesn't hit the OB where it needs to. That's a much smaller margin of error.
