Here is another comment to supplement my previous post.

This graph shows the kinetic sequence in an excellent swinger's swing.



The graph is from Philip Cheetham of TPI.

Note how the angular speed of rotation of the hips/shoulders/arms is the same in the early downswing. Then note that the pelvis slows down slightly before the shoulders, and that the shoulders slow down a little later, just before the arms reach peak velocity. Note that the arms reach peak velocity when the hands are at waist level - in the mid-dowswing. Note that the arms are moving at a slower speed in the late downswing, but that the clubhead is rapidly accelerating in the late downswing to reach maximum velocity at impact. The reason why the club is moving so fast in the late downswing is due to the release phenomenon (release of power accumulator #2). Considering how fast the club is moving in the late downswing due to the sequential release of power accumulators #4 and then #2, how could an active release of power accumulator #1 at this same time-point in the late downswing increase clubhead speed? Remember that the the right elbow is straightening in the late downswing at the same time as the clubhead is traveling at an ultra-fast speed. How can any active isotonic contraction of the right triceps muscle at this same time-point in the swing get the club to move faster than is demonstrated in this diagram.

Maybe that is why Hogan "wished he had three right hands". He wished that he could get the club to move faster in the late downswing, but practical common-sense probably made him realize that his swing was already optimized for maximum clubhead speed generation., and that any attempt to add extra swing power in the late downswing was not practically possible for a swinger who had a perfected triple barrel 4:2;3 swing.
