Anyway, the guy is saying he is finding that his shot form is inconsistent. Here's what you do to make it consistent. Work out and do form shooting (skip to 0:40):
Start doing this right in front of the basket. When you make 3 swishes in a row, take a step back and repeat process; make 3 swishes in a row and take another step back, etc. If you miss 3 shots in a row, take a step forward. This also works as a range finder.
Make sure you are holding the ball the same way every time you shoot too. You want your fingers to be spread out as much as possible on your shooting hand.
