If "right arm participation" = unbending your right arm using the tricep muscle, I'm curious how what you've described is different from extensor action as Homer defined it?
6-B-1-D EXTENSOR ACTION is exclusively the steady effort to straighten the bent Right Arm
Extensor action is Non-Accelerating the primary lever assembly
Right Arm Drive is Accelerating both lever assemblies
The key is Nonaccelerating vs. Accelerating
Acceleration is a change in distance over a change in time
Hard to pick up visually for the untrained eye...
OK, So then a better question for Jim would have been...is his "right arm unbending" a steady or an accelerating action?
The reason I ask is because it seems that if you accelerate the right arm unbending at all, won't you feel the results of that action through a pressure point? If so and it's not pp1, then which pp is it?

It is an accelerating action that i only start to do consciously around what my brain interpret's to be release point (hip high).
Honestly, it is too quick of a motion to really feel anything anywhere. I am just trying to wallop the ball

1-F RIGHT ARM OR LEFT The “mystery” of the Mechanics of Golf fades away when Right Arm participation is understood (6-B-1). Whether its participation is active or passive is difficult to detect visually because in either case the Left Arm is ALWAYS SWINGING and the Right Forearm is ALWAYS DRIVING. . . .
This, alone, does not properly separate “Hitters” and “Swingers” because it is possible to “Swing” the Club with either Arm but only the Right Arm can actually “Hit.” See 10-19. However, you will save yourself much anguish by using the Right Hand just for sensing and controlling acceleration and the Left Hand just for sensing and controlling alignments.
7-3 STROKES – BASIC . . . The Elbow must always be someplace and as there are only three defineable locations there are three Major Basic Strokes – Punch, Pitch, and Push (10-3). . . . The Elbow must always be someplace and as there are only three defineable locations there are three Major Basic Strokes – Punch, Pitch, and Push (10-3). . . . So the Right Forearm must leave – and precisely return to – its own Fix Position (7- “Angle of Approach” (regardless of the true Clubhead Angle of Approach) because both procedures will produce identical Clubhead Delivery Lines. . . .
, it is absolutely MANDATORY that, Hitting or Swinging, it is the Right Forearm – not just the Right Hand and/or Clubshaft – that must be thrown, or driven, into Impact per 7-2-3.
Acceleration is a change in distance over a change in time
Actually it is a change in velocity (dv) over a change in time (dt). Sorry about the nitpicking, but just trying to make sure we have a physics compliant site.

Average Acceleration = Change in Velocity divided by a Change in Time
Now are we talking:
Linear or Angular Motion
The formulas vary slightly for both
Theta = Arc Length divided by the radius
Omega = Average Angular Velocity equals a change in theta divided by a change in time
Alpha = Average Angular Acceleration equals a change in omega divided by a change in time
Arc Acceleration = alpha times the radius
Centripetal acceleration = Omega squared times the radius
Centripetal Force = Mass times Omega Squared times the Radius
Centrifugal Force = Newtons 3rd Law to Centrifugal Force
Documented Source: "Biomechanics of Sport and Exercise" 2nd editon, Peter Mc Ginnis, Quick reference equations, p.1.
Why weren't these formulas used in the Yellow Book? Bibliography? Documented Sources/ Footnotes?
That's Ok.....I believe Homer anyway....28 years of work very impressive...but I work for a University...If I submitted that wonderful piece of work...the Dissertation Committee would have told me nice try and re-tee!!!

Those equations look mighty fine although strange to my eye. I have never seen them written out in English. I am so used to the Greek letters / mathematical forms, I had to re-read these several times to understand.

Sorry don't know how to type Greek....My keyboard is American English as my British friends always take a jab with their light saber.........
But they are legit and documented......Stragiht from a Graduate Level Textbook used here at the Universtiy that is taught by Dr. Brian Bergerman...who has a Ph.D in Biomechanics and is one of the world's leading experts in the ther track and field event of "pole vaulting".....
BTW ...Dr. Bergerman sat on the Dissertation Committee for Dr. Ralph Mann the "Father of Model Golf".....First Question Dr. B asks...'So what do you think of Ralph Mann's work?"....Well I would never use the "Mean" to come up with a Model...I would classify them into "modal classes"...For example hitters and swingers...Pure hitters and switters...Pure Swingers and Right Arm???? Not gonna say it!!!!
We have talked about this before... but I heard this from a man that is very physics savy... Is the horse Pulling the wagon, or Pushing on the collar? You would have to ask the horse to know.
Technically... there may be little or no difference, but FEEL-wise there usually is.
“Angle of Approach” (regardless of the true Clubhead Angle of Approach) because both procedures will produce identical Clubhead Delivery Lines. . . .
Hybrid Mode
