I would think for a given shot and relationship to the pocket that certain borderline shots especially could be perceived differently. I don't think the objective aim points A/B/C etc. change, just our perception of them or what is needed to make the shot.
But I would also bet that most skilled Pro1 or SEE practitioners would see 98%+ of the shots the same way. I know for me, I'm still working on longer shots, standard Pro1 and SEE teachings have you aim as if the shot was thicker (A/C instead of B, STC instead of STE), but I've had good and bad results with both. So it's just something I need to put more work into and do some trials while keeping track, that way I can nail down what works for me and have the confidence to reproduce it during a game.
