It's interesting that the first sentence of 10-20 of the 7th edition which is a change from the 6th and it reads...."Trigger Types are classified according to the point of origin of the action." That seems to be consistent with Tommy's explanation on section 20 FOR SWINGING. Five ways to start the downswing...which I believe is consistent with Longitudinal Acceleration. As Tommy said "one smooth motion"....
"Point of Origin" in 10-20 refers to the originating point of the Action that Triggers the Release. In other words, the locushttp://www.merriam-webster.com/dictionary/locus of the Triggering Action. Is that locus the Hands (10-20-A)? The Right Arm (10-20-B)? The Right Shoulder (10-20-C)? The Left Wrist (10-20-E)? Or, for Automatic applications, the end of the Delivery Path (usually in Combination with either the Right Arm or Left Wrist / 10-20-D)? Or in some other Combination (11-20 lists some, but certainly not all)?
The quote emphatically does NOT apply to the three Release Points (Sweep, Random and Snap) or Release Types (Full Sweep, Random Sweep, Snap and Flip). While the Variations of the Trigger (Component #20) and the Release (Component #24) are ordered to reflect their parallel nature, the Release Points and Types are specific to the Release Component (11-24).
I continue to post in this thread because I believe there is value in refuting -- by differentiating with the facts and appropriate references -- the misinformation attributed to Tom Tomasello by his most ardent proponent.
I believe that Peter learnt TGM from TT, and I can sense TT's influence in his swing methodology.
The first photo series summarises Peter's swing methodological approach.
1) The idea is to get the clubhead down to the ball as fast as possible using the hands to throw the club.
2) The body reacts to the hand throw and does not initiate the downswing action with a pivot-drive.
3) The hand throw must throw the clubshaft down-and-out on plane - the plane of the uncocking left arm.
4) There will not be an early release (clubhead throwaway) if the throw is on-plane - see his photo series. One can see that Peter maintains his power package assembly intact in photo 2.
In a spirit of intellectual curiosity I have experimented with this technique, and I believe that it is a very viable method of swinging.
Consider the technique of swinging the hands down-and-out "on-plane".
One option is TT's right arm throw method. In that method one is using the right arm to throw the left arm/hand down-and-out. In the first part of the throw sequence, the right arm is adducted to the right side and the right elbow positionally approximates the right hip area (photo 2). This action drives the left arm/hand down-and-out on the plane (while keeping the left and right flying wedges intact). In the second half of the right arm throw action, the right elbow actively straightens applying pressure to PP#1 thus causing the left arm/hand to continue its down-and-out movement. Eventually PA#2 releases by centrifugal action and finally PA#3 releases automatically (as Peter describes in his tennis raquet sequence).
From my perspective, there is potential danger to throwing the left arm/hand down using this "right arm throw" technique. If one is driving the left arm/hand down-and-out onto the plane using a right elbow straightening action, then it is possible for the active right arm thrust to i) over-accelerate the left arm/hand too fast into impact and providing insufficient time for the complete passive release of PA#2 and PA#3; or ii) the right arm thrust may produce too much push-pressure at PP#3 thus causing the clubshaft to be driven forward in a hitting action. That will interfere with the centrifugal release of PA#2.
I think that a better method of throwing the left arm/hand down-and-out on plane is to simply pull the left arm down-and-out onto the plane while aiming one's hands at the ball (aiming point). This allows for a passive centrifugal release of PA#2 and a natural/automatic release of PA#3 without any interfence by the right arm/hand applying push-pressure at PP#1 or PP#3. In this method, the right arm/forearm/hand's only contribution will be to i) apply extensor action throughout the swing; ii) sense clubhead lag at PP#3; iii) maintain the clubshaft on-plane through the magic of the right forearm. The right arm will be not be used to power the downswing left arm/hand throw action.
This might be the difference between a "hand motion" controlled pivot and a "hands sensation" controlled pivot...no...those terms are not in the book but ...
The book and TGM tend to focus on learning through sensing lag pressure...once sensed the pivot can direct the hands along a delivery path appropriate for the shot. The book mentions taking sufficient time at "top" to plot the required path for dwonswing.
But this system requires time for lag sensation to be experienced at loading...brain then computes required delivery path...then action taken.
What would happen if the brain automatically moved the hands along a preprogrammed delivery path...without any conscious waiting for lag pressure.
To a player it might feel like "just moving the hands"...
maybe?? more fuel to the fire... and either way - I suspect that the body moves first anyway!

And I'm sure I won't be the last ardent proponent.

For Swinging...."Centrifugual Force Uncocks BOTH the Left Wrist and the Right Elbow." Reference 7-1. Even after telling me to start the club down with the right arm Tom Tomasello reference that sentence in 7-1.
As Tommy said...."the learning is never ending." GI 1991.
