Another thing I HAVE to do is remember to fully rotate my release hand to a vertical position every time. I was getting mixed results rotating to differing degrees.
I'm not sure if Larry's book that Matt's sending you will say anything about it, but as you can see Dave up above in Matt's post, most recommend NOT turning your hand all the way to vertical, as it places stress on your forearm at the shot.. just something to consider before you begin ingraining a motion in your memory.
