Non-Accelerating Thrust Versus Accelerating Thrust

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).
Thanks for the reply Yoda. I think you cleared up my confusion about Extensor Action in Hitting but not Swinging, yet maybe I'm still confused about both. 6-B-1-D says the exclusive steady effort to straighten the bent right arm stretches but doesn't move the left arm. So when a Hitter begins to move the left arm with triceps acceleration, does Extensor Action end, and if it doesn't, is there now a dual force that both stretches and moves the left arm?
And what about THE MAGIC OF THE RIGHT FOREARM description that reads "Bending and Straightening the right elbow will Raise and Lower the Left Arm and/or Cock and Uncock the Left Wrist... Does the "and" of "and/or" apply only to Hitting and the "or" only to Swinging?
I'm not sure what most AI's will say when asked what moves the left arm away from the right shoulder to allow the right arm to straighten during Swinging per 6-B-1-0 so I'd like to hear from you in that regard.
Lastly, I think the folowing excerpts from an early TGM edition points out that Kelley may have struggled with this whole issue as well. "The 'body' is considered herein, primarily as transportation, guidance, and launching pad for the Power Package, rather than a power 'source'. An attempt to hit a ball using nothing but Body motion, and hitting a ball with with no body motion (Non-Pivot), will point up the correctness of this contention.... So Power Package Muscle Power is ideally 95% Right Triceps. The Right Triceps and Pectoral can handle the muscle requirements of the Downstroke and need no help from those on the left, whose feeble contribution makes any such thing as a true Left Arm Power source pretty much a myth."
I wonder if anyone has all the editions and can find this quote. I'd like to know if Kelley was referring only to Hitting when he wrote this. I don't think he was.
6-B-1-D says the exclusive steady effort to straighten the bent right arm stretches but doesn't move the left arm.

I'm no expert but it seems to me to be a question of the direction in which the right tricep is exerting force. For extensor action - down the line of the left arm, for hitting muscular thrust: down , out and forward on plane. So I think is just a case of the direction the thrust of the right tricep is in - if (for simplicity's sake) extensor action was down V and hitters thrust was forward > then hitting with extensor action is both down and forward (for which there is no key on my keyboard!) - hitting without extensor action is only forward.
Of course there is also the accelerating, non-accelerating issue - but I think this is taken care of by the fact that the left arm is tethered to the left shoulder. Theoretically, one could attempt to apply as much accelerating force as one wanted down the line of the left arm - it won't accelerate, until the point when the force gets great enough to rip the arm off!
I truly believe at no time does the golfer actually exert direct force with his or her triceps...the triceps react in all procedures to either the triggering action of a driving right forearm or pivot thrust. I believe that's why all three procedures produce accurate golf shots...and that's why section 20 is called trigger types...
Three barrel swing (with momentum transfer, Low hand-speed)
Four Barrel Hit (momentum transfer and a driving right forearm)
Right Arm Swing (driving right forearm, less momemtum transfer, high hand-speed with full sweep release).
Just different trigger types putting the right triceps into action...that's all.
The one major advantage of using the Right Arm swing is a change in focus..from one of physics and power to one of imagination through hinge action. Those who use the right arm swing and the 3 barrel hit will know what I mean.

Does this have the net effect of putting clubface control in the right wedge? Not sure if I follow what you mean by "imagination through hinge action" when related to the right arm?

sounds like for hitting the right elbow needs to be in front of the right hip so body supports the right arm thrust---and for swinging it is not needed as such but rather for the delayed release--is that right ??

The Golf Stroke is very dependent on the location of the right elbow so that the right forearm can function accordingly. Three elbow locations - Punch- at the side, Pitch- in front or Push- up and out behind the shaft.
Hitters would use Punch- elbow at the side to drive the right forearm and right hand. Swingers are more identified with the Pitch Elbow location as the right elbow gets deeper into the Stroke Pattern with a Maximum (late) trigger release to whirl the clubhead around a smaller pulley. A swinger could use Punch with a Sweep type release, too.
Push is a chip or putt stroke.

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.
