What get's the right elbow into a push position, rather than a pitch position?
I suspect that it may be due to a non-optimum downswing pivot thrust action.
Here is a swing video of Ben Hogan.
I think that he gets his right elbow into a pitch position due to a "correct" downswing pivot action. Then, when he lets go and completes the downswing (at time point 33 seconds into the video) he
fully releases PA #4 so that his left arm swishes across the front of the body.
I suspect that some switters are not using the pivot thrust properly to
fully release PA#4 (like Hogan) and that they are only driving the power package down to waist level with their pivot action. Then, they use an active release of PA#1 to drive the left arm forward (to fully release PA#4) - they "hit at the bottom". Biomechanic argues that tour players do this (hit at the bottom) but I don't agree. I would be interested in reading Yoda's opinions on this issue.
