I suppose my response would be that I train to the standards I train to not because I actually expect to have to make those shots at those speeds but because getting shot at, or shot potentially, is going to lower my ability to make decisive hits and the better I can make those hits in practice the better I can potentially make them when it counts.
Switching to fsf and knocking the apple out at 25 makes it more likely that I can do the same at 10 during an adrenaline dump. Dots are easier to reliably do that with with less practice. I don't think I'm telling you anything you don't know. I agree that it's unnecessary to throw a "need" in there. But reading between the lines, that's what I'm reading.
