Thank you for the clarification. It is now much more precisely expressed, and it is now 100% concordant with many statements that you have previously made in your archived posts. I was worried that I may have misunderstood your previous archived posts when I first saw the phrase "driven by that action". Your now preferred use of the term "motion" promotes a very different understanding of the biomechanics of the right elbow's motion.

You state that TT is implying a right hand/wrist throw. That "belief" really confuses me because I have understood TT to believe in HK's teaching that the right wrist should remain bent throughout the downswing and early (+/- late) followthrough. If the right wrist remains bent, then it is not released, so in what sense is the right wrist/hand thrown (in a way that doesn't involve the elbow joint)?
You also quote as "evidence" for your belief that Hogan used an active right hand/wrist throw the following Hogan statement -: "I wish I had three right hands."
You obviously have a very different understanding of what the word "evidence" means with respect to understanding the biomechanics of a particular golfer's swing.
