just use the practice mode to practice on the release point...
BUT if you cannot be bothered, or still cannot find that perfect release point, go into the sliders, and
change the poor release point in the user sliders to 0
Your player will now always release it perfectly, but it doesn't mean your game stats will be 100% fg but it'll just mean the computer won't randomly make your player jack up off balance shots for no reason.
So if u're player is open he WILL sink the shot, if he's being guarded, he still has a chance of missing the shot.
