Considering that the hips move at around 2mph for only a short distance and the shoulders at around 5mph for not much further, you have to question just how much effect they have on swing speed - and it is swing speed (Homer's version of "Power Accumulation") we are talking here not "torque" or any other power generation as commonly spoken of outside of the TGM fold.

The pivot, hips and shoulders, et al, is, by and large, only a transportation medium for the lever assembly - the swinging arms and club.
