The one thing about your approach is that you are unwilling, or unable, to describe TT"s right arm throw action in detail.

You make statements that are vague like -: "Then please tell the class why Tommy started the downstroke with everything (uncocking of the right forearm, the right shoulder, the right forearm and left forearm, the left wrist) for full golf swings per the TGM swinging procedure."

What does it mean to say that TT started the downswing with "everything"? Surely you need to explain the sequence of events in great detail?

In your last post, you stated-: "lever and unlever the right forearm." That's not a complete explanation. That's a vague statement.

Don't you think that you should offer a more detailed explanation of TT's "right arm throw action" if you want us to consider it a viable option for swinging a golf club? For example, you make statements like "throw the right arm from the top". Yoda has questioned the rationality of the idea that one can throw the right forearm from the top, and I think that he has a point. When I look at TT's right arm throw action, it reminds me of a person skipping stones. When a person skips stones, I believe that the right forearm throw action only starts after the right arm is adducted to the right side and the right elbow is wedged into the right hip area. In other words, the "right forearm throw" action only starts in earnest when the right hand reaches waist level. There must be a preceding downstroke movement that initiates the stone skipping action - for example, transferring weight to the lead leg with a pivot motion, and bringing the right elbow down to the right side by adducting the right upper arm (which involves right shoulder girdle muscles).

Also, in a stone skipping motion, the right elbow straightens and the right hand releases the stone. However, golf requires the two arms to work together because the two hands conjointly hold the grip end of the club. If the right arm throws the right hand, then the right hand must be moving the left hand because it is conjoined to the left hand at pressure point #1. Therefore, you have to explain what "effect" the right hand has on left hand movement and whether there is also a release of PA#4 via some other mechanism, and whether the right hand movement has to be coordinated with the left hand movement (secondary to the release of PA#4).

Also, here is a capture image of Tiger Woods swing - from the Nike commercial video.



I used a spine tool in my swing analyser program to make a white dot every 10 frames and that works out to one white dot every 1/400th second (because the video frame rate was 4,000 frames/second.) Note that Tiger's left arm speed slows down just before impact, and that allows PA#3 to release completely so that the clubface can be squared at impact. In a "right arm throw" swing, how does a golfer get the hands to slow down just before impact to provide enough time for the complete release of PA#3?
