Thanks for your insightful posts, Coop. You've got everybody thinking and learning. As it should be!

Regarding your question...

In addition to Clubhead Lag Pressure (Acceleration Control per 6-C-0-3), there are two types of Thrust: Non-Accelerating and Accelerating. Extensor Action is a Non-Accelerating Thrust that supplies Power Package Mass (6-C-0-2). Used by both Hitters and Swingers, it stretches the Left Arm (in the direction it is pointing -- Below Plane) but does not cause it to move. Hence the modifier Non-Accelerating.

On the other hand, the Hitter's #1 Power Accumulator -- Right Triceps/Elbow Drive-Out -- is an Accelerating Thrust (6-C-0-1). Applied On Plane against Pressure Points #1 and #3, it does move the Left Arm. In fact, it moves both the Arm and the Club (the entire Primary Lever Assembly). You could say that the Accelerating Thrust (Right Arm Drive) Pushes the Non-Accelerating Thrust (Power Package Mass) Down Plane through Impact to the end of the Follow-Through.

Swingers use the Right Triceps to produce only the Non-Accelerating Thrust of Extensor Action. Centrifugal Force -- that phenomenon induced by rotation that causes the Club to seek its In Line relationship with the Left Arm -- provides the Acceleration Thrust (6-C-0-4).

Lynn,

First, in 6-C-0, there are 4 types of thrust...you indicate there are only 2.

Second, the comment about extensor being non-accelerating, I would agree that relates to swinging....with a swinging procedure that utilizes momentum transfer and NO right arm thrust as explained per 6-B-1-D-4.

If hitters can use an extensor action accelerating thrust...I would think right arm accelerating thrust is available for the swinging motion that Tom Tomasello taught. Wouldn't that be confirmed by the commment that Homer makes in the middle paragraph of 6-B-1-D where Homer says, "Extensor Action gives an indispenable control to all Strokes".

How about Homer's comment in the third paragraph of the 5th
edition where Homer writes, "A Ball-related Release (10-19-0) for Swingers can be produced by using Right Arm Thrust instead of Body Momemtum to resist Clubhead slowdown during extension, if there is sufficient Clubhead inertia to restrict Lag Pressure thrust (6-C) to only an Extensor Action application (6-B-1-D, 2-M-3). Its execution must produce a true centrifugal Throw-Out action as outlined in 6-B-3-0. This Throw-Out action is termed herein as "Centrifugal Acceleration" to indicate that Centrifugal Force (Centrifugal Reaction), not muscle, is propelling the Secondary Lever Assembly (the Golf Club) into Impact. So Swingers are totally dependent on their skill at manipulationg Centrifugal Force while Hitters are not. But study 4-D, 6-F-0 and 6-R-0.

Then the comments from Tom Tomasello from his 1991 GI interview where Tommy says..."The only agility needed by the player is to be able to turn the hips--to pivot around a fixed point--and to lever and unlever the right forearm. The faster you can make these two movements, the greater the centrifugal force you'll build up and the farther you'll hit the ball.

From the above comments, it appears to me centrifugal Reaction can be generated from more than once source, pivot thrust or power package thrust...it appears the basic requirement is accelerating the club longitudinally, which can be executed with Pivot Thrust or Power Package Thrust (see Hitting and Swinging per page 235), I believe the problem lies in mixing them...which, Tommy Tomasello didn't do.
