[O.B.Left]

"As soon as your left hand leaves its flat to the inclined plane condition in the Downstroke".


Ok where in relation to the body does this action take place?
When the hands are hip level, thigh level, hands are even with the ball?

The other way of posing this question is "where does Release take place?".

Full Sweep Release would have it happen very early for a high floater around the green or a shot over a tree or something. A knock down would see it happen later as you add shaft lean. Delayed Release for added power, early Release for a higher trajectory , etc etc . Release is one of the tools of the shot maker. A machine adjustment.
