We obviously disagree on many points.
It is true that the hosel rotates around the sweetspot when one rolls the club on a tabletop. However, that happens because the clubshaft is rotating around its longitudinal axis with no lateral movement of the entire clubshaft in space. That phenomenon doesn't happen in the golf swing. The clubshaft only rotates in space due to the fact that the left hand rotates in space - due primarily to the movement of the left arm in the left shoulder socket while the left shoulder socket simultaneously moves in space because the upper torso rotates in space. If a golfer has a synchronised swing - where the arms rotate synchronously with the rotating torso - then most of the rotation of the back of the left hand, and therefore clubface, will be due a global/proximal movement and not due to the clubshaft rotating independently around its longitudinal axis. That's what I tried to demonstrate with the Jack Nicklaus composite photograph.
I would like to see you attempt to present a solid TGM-based argument that demonstrates that the straightening right arm controls the rate/rpm of rotation of the left hand/clubface. It is my belief that the left hand controls the clubface via the biomechanical action of a hinging action (variable degree of external rotation of the left humerus in the left shoulder socket while the torso continues to rotate).
