10-19-C ...Start the Club down as though it were being drawn from a quiver like an arrow-feathered end first. Maintain this motion until the Release switches ends. This is possible only if, and for as long as, Inertia can hold the clubhead inside the arc of the Hands or hold to a Line Delivery Path (2-L). Centrifugal Force will set in when the Clubhead crosses to the outside and it will begin to pull into its own incidental orbit per 2-P and 2-K#5. Then further acceleration can be applied only at Pressure Point #1 to support the Pull on the Clubshaft-especially for Short Shot Power.

I can understand now how "an arrow out of is drawn out of a quiver" with the swing of early Hogan I made. Please share what Homer meant by the words in bold.

I will venture a guess at what Homer meant. Knowledgeable TGMers can correct me if I am wrong.

Homer talks of the release switching ends. That presumably happens after the delivery position when the release phenomenon happens. Prior to that point in the downswing, the clubhead is in inside the arc of the hands, but after release (at approximately the delivery position) the clubhead is outside the hands - as demonstrated in this photo of Badds.



This image shows the clubhead being inside the hand arc (when the clubshaft is in line with the right forearm), and then moving outside the hand arc due to the release phenomenon.

After release (due to release of power accumulator #2) the clubshaft is accelerating due to centrifugal action, and a swinger can no longer get the clubshaft to travel faster due to muscle power "pushing" the clubshaft forward at the grip end. A swinger can only use right arm/forearm muscle power to apply "push" pressure at the grip end of the clubshaft (specifically at PP#1) to support the "pull" action already in play due to the release of power accumulator #4.

Interestingly, Homer used the word "acceleration" in that last sentence, and it is not clear to me whether he is referring to acceleration of the clubhead or acceleration of the hands. If he is referring to acceleration of the clubhead, then I do not understand how this is possible, because according to Homer's endless belt analogy, maximum clubhead speed is attained at the start of the release and not necessarily at impact. I, therefore, presume that he is referring to acceleration of the hands. However, even this point is interestingly mootable, because this graph shows that the arms decelerate prior to impact.



Interestingly, according to nmgolfer's mathematical explanation of the release phenomenon, the clubshaft can constantly accelerate all the way to impact, even if hand speed remains constant or decreases - as long as the club can acquire further angular acceleration due to the hand "pull" force being at an angle to the COG of the club.
