When you state that the clubshaft is parallel to the ground, then you must surely be referring to the delivery position. You then imply that Hogan's clubface is square at this position with the right palm facing the ground. I do not see that phenomenon in Hogan's swing. Do you have a single photo showing that Hogan's clubface is square to the swingarc when his clubshaft is in the delivery position?

From my perspective, Hogan would have wanted to avoid that scenario because he had a hooking problem and he apparently wanted his clubface to be slightly open throughout the early/mid downswing. Jim McLean makes this point in his DVD series analysing Hogan's swing.

Here is a photo of Jim McLean mimicking Hogan's swing action when his clubshaft is at the delivery position.



The dotted yellow line shows that the clubface of Jim McLean's club is slightly open at this time-point. Jim Mclean stated that Hogan deliberately maintained a slight cupping of the left wrist throughout his downswing so that he could keep the clubface slightly open to the clubhead swingarc.

If the clubface was square at this time-point in the downswing, then the back of Hogan's left hand (which is parallel to the clubface) must be facing slightly groundwards. I have never seen a photo of Hogan at this time-point in his downswing with the back of his left hand facing groundwards. If anything, it always seems to face slightly skywards.

You also wrote-: "The hip turn that starts the downswing (i.e. left side of the body action - remember Hogan's image of elastic tape glued to his left hip ?) is a pulling motion that can create by itself the left wrist cock. Supposing that Hogan used his right arm/elbow/forearm/hand to support the hit, he had to convert the left wrist cock lag into a right wrist hinge lag."

I don't think that you understand Hogan's swing action from a TGM perspective. Power accumulator #2 is loaded during the backswing and that establishes the left wrist cocking angle of =>90 degrees. When the left wrist cocks up during the left arm's lifting/counterclokcwise rotation movement, the right elbow folds and the right wrist hinges back into a bent right wrist position. Therefore, the bent right wrist situation is established during the backswing. Once established, the bent right wrist is never released during the downswing, even when the right elbow straightens in the late downswing, and even when the left wrist uncocks as power accumulator #2 is released.
