I am willing to take time to understand your viewpoint because I know that you are a serious student of Hogan's swing. However, I can only understand your viewpoint if you express it in sufficient detail that I can grasp what you are implying.

What do you mean by "squaring the clubface in the late downswing"?

What do you mean by the "right palm-down" position?

What do you mean by "conversion of a left wrist cock lag into a right wrist hinge lag"?

What do you mean when you state that the "right elbow moves independently more than the pivot suggests"? When does this happen? Are you implying that the right elbow moves independently, and out of synchrony, with its right arm flying wedge relationships?

It is interesting that you made this statement -:"not possible to do it by only pulling with the left arm"?

I wonder whether we have the same conception of HK"s description of a swinger's swing. It is my understanding that HK stated that a swinger uses a triple barrel swing - 4:2:3 - and that the release of power accumulator #1 is not active. From my perspective, that only means that power accumulator #1 doesn't apply additional "push" power over-and-beyond that required to supply continuous extensor action via PP#1 and more than is necessary for the right elbow to straighten at a rate that is synchronous with the left arm pulling away as a result of release of power accumulator #4.

Yoda can correct me if I am wrong. However, this is my perception of a swinger's downswing action - like Hogan's downswing action.

A swinger (who is not an arm swinger, but a body swinger) initiates the downswing with a downswing pivot action starting with the lower body and then involving the upper body. During the early/mid downswing, the torso moves as fast as the arms, so that the entire power package remains intact until the hands reach waist level. Then, the downswing pivot action subsides and that causes the left arm to be catapulted off the left shoulder area thus widening the angle between the left arm and upper chest wall between the shoulder sockets. From this time-point onwards the arms are moving faster than the torso, and this represents the "effect" of the release of power accumulator #4. When the left arm is moving faster than the torso, it is indeed pulling the grip end of the club in a longitudinal direction. However, that doesn't mean that the right arm/forearm is passive. During the mid downswing, when the distance between the left hand and the right shoulder is increasing as a result of the release of power accumulator #4, the power package structure remains intact and the right elbow is still bent at a right angle. I think that it is only possible to maintain these power package relationships if the right arm/forearm muscles are isometrically active. In other words, I believe that the right arm/forearm is very active in an isometric sense during the downswing, and it is only correct to state that the right arm/forearm is passive from an isotonic perspective (which means that the right triceps doesn't shorten and actively straighten the right elbow, and the right forearm flexor muscles do not shorten and palmar flex the right wrist). However, the right arm/forearm muscles must be very active from an isometric perspective for a golfer to maintain the right arm flying wedge relationships and to also maintain constant extensor action throughout the downwswing. I also believe that the isometric contraction of the right arm/forearm muscles allow a golfer to "direct" the right forearm to remain "on plane" and avoid a situation where the left arm flies away from the body during the mid-late downswing (as you implied). It is the right arm/forearm that keeps the clubshaft "on plane" during the downswing and that would not be possible if the right arm/forearm muscles are not actively contracting. However, that doesn't mean that the right arm/forearm muscles are supplying "push" power in the sense of actively releasing power accumulator #1. HK suggested in his TGM book that one shouldn't "pull" and "push" at the same time, which is why he stated that a standard swinger's action (non-right arm swinger's action) can only be a 3-barrel action (4:2;3) and not a 4-barrel action (4:1:2:3).
