I've never seen someone hit the ball from a position rear of centre and have a divot that reaches past the left shoulder. Obviosly I'm not watching the right people.

Opposite the left shoulder as viewed from what angle?

Hmmm...

My guess is that there is a theoretical low point and an actual lowpoint. For a stroke where a divot is taken, the clubshaft is bent backwards, and remains bent backwards as the shaft drags the clubhead through Mother Earth. It seems to me that would move the actual lowpoint of the swing back from the left shoulder. For a stroke where there is no contact with the ground (e.g., driver), the theoretical and actual low points are the same.

Any comments?
