By the time someone gets to college. This is for a number of reasons but the 2 biggest are that they've (hopefully) gotten tens of thousands of reps in shooting a certain way, so knocking that all down to rebuild can take much longer than you're able to wait The second is that you have very limited time with your players off-season, and you certainly don't want to change your shot in-season So the best way to make someone shoot a better percentage at the college level is to make more subtle changes to make their current form more repeatable. As someone said down the thread consistency is better than form at this stage. If I'm teaching college kids I don't really care about the turn, I don't really care about the middle finger flick. I care a little more about getting your elbow under the ball. But some things you didn't mention that are bigger teaching points with older players (i.e. college level): Spreading your hand out across the ball for better control 1-2 rhythm when catching for a shot (catch on 2 feet if theyre an advanced shooter) Landing in the same place you jumped from (drawing a box around their feet and have them make 100 shots from the box, any makes landing outside the box don't count) You can do a lot of things differently that you developed in childhood, but if you do those things above you'll turn yourself into a serviceable shooter
