Daryl - you wrote-: "#3 starts after #2 release begins but it is also spent before #2 is spent. #2 release starts after #4 release but it gets spent before #4 gets spent."

Why do you believe that #3 is spent (completely released) before #2 is spent. What is your definition of a spent #3 and a spent #2?

You also state that #2 gets spent before #4 is spent. I thought that #4 is spent at low point.

Good questions! Brain Teasers.

#3 stops swiveling when the Left Wrist is Vertical to the Ground, which is Technically 10-2-B with a Forward Leaning Shaft at Impact (even if the Left Wrist appears to not be Vertical, the Right Wrist is Vertical and Level). Swivel on the Backstroke and on the downstroke you swivel-back-to-the-Hinge. Any further Closing of the Clubface is Hinge Action Pivot Roll (otherwise your divots would look really funny - a straight thin line parallel to the plane line). So the Impact Interval Ends the Acceleration of #3.

#2 is Fully Uncocked at "Lowpoint" and the Law of the Flail states that Fully Uncocked is the Point at which #2 begins deceleration. So Lowpoint Ends the Acceleration of #2.

When does #4 stop Accelerating? #4 decelerates when the Left Arm stops accelerating away from your chest which is "Both Arms Straight" or further hopefully, if possible.

So, The Acceleration of #3 (Swivel plus residual #2)is in addition to the accelerating #2 and which is in addition to the acceleration #4. And, the acceleration of #4 is what Releases #2. The Release of #2 creates centrifugal force which Releases #3.

It's like throwing a ball while running on a moving train.

Daryl,

Thanks for commenting.

I can accept your endpoints for a spent #2 and #3, but not #4.

You write-: "When does #4 stop Accelerating? #4 decelerates when the Left Arm stops accelerating away from your chest which is "Both Arms Straight" or further hopefully, if possible."

You "seemingly" believe that the left arm is accelerating to the end of the followthrough. I cannot understand that point. In a pivot-driven swing, the inert left arm gets all its swing power from the pivot-drive. In other words, the pivot-drive catapults/blasts the left arm off the chest wall towards impact. I believe that the left arm must start decelerating the further it gets away from the chest wall - because I know of no other force that can keep the left arm accelerating during the late downswing (near-impact) and during the post-impact followthrough phase of the swing.

Here is a graph from the TPI researchers showing that the left arm decelerates prior to impact.



Here is a photo from the Nike commercial swing video of Tiger Woods swing (taken at 4,000 frames/second).



Each white dot (showing the left hand motion) represents 1/400th of a second. The white dots gets closer together just prior to impact - which suggests that the left arm slows down slightly prior to impact.

The TPI researchers show you what most Golfers do. They are measuring Speed, not Acceleration Forces. They don't show you what most golfers should be doing. That's a problem with these researchers. They don't know about the possibilities and the Options. They take measurements and tell you what they are. Those kind of people will tell you to swing harder. They will tell you to over-accelerate and they don't even realize that over-acceleration is the problem. The researchers who supported "The Search for the Perfect Swing" didn't know either. Homer Kelley knew.

TPI are like the 'washing machine repairman'. Ask them why it doesn't work, and they reply 'because it's broke'.

Jeff, forget about the cameras and pictures for a minute. The Hips are leading and powering the Right Shoulder which pushes the Left Shoulder which pulls the left arm. Pivot Train.

The initial Blast off the chest of #4 happens because of Right Shoulder Thrust became less than the Velocity it produced. Over acceleration will blast the arm away from the chest too soon every time. Homer Kelley said "Instant Hip Acceleration", he didn't say 'do it so fast that your left arm blasts off of your chest pre-maturely'.

Thrust is the "Rate of the Acceleration" not the "Acceleration" (which is the rate of Velocity). SO, the Thrust moving the Left Shoulder dictates the Rate that the Left Arm will accelerate and requires only that the Pivot train keep moving, even without accelerating itself. The hips pull the Shoulders through the Impact Interval and beyond at a steady speed to provide an increase in Mass. The Left Arm may have started at Zero MPH at the Top of the Swing and reached its maximum speed in MPH at or just after impact, but it is still an Accelerating Force that doesn't diminish until the Hips Stop Pulling and Leading the Shoulders.

The Clubhead should reach its maximum speed three feet after impact, or at least that’s what you should be trying to do. That's the #4 Accumulator. If you don't have that, then you're just simply going around in a circle. It's not how fast you move your Hips...it's How Far you Move Them.

Do the TPI Models look like this guy? Your TPI model is using a Hand Throw from the End of the Backstroke (A very Questionable procedure) . Even the Model has 'stopped the Pivot' to avoid a pulled shot. And he's just a simulation. Geez. My guy uses a Shoulder Throw followed by a Wrist Throw.




Additionally, Consider this. When a baseball Pitcher throws a pitch,,,,,the ball keeps accelerating because the pitchers rate of acceleration (Mass) at release was increasing. The Ball is slowest MPH when it leaves the Pitchers hand and fastest in MPH when it crosses the plate. Hmm? I wonder what the TPI researchers would say to that?? I bet that they would tell him to 'Back up a Bit'.

We "seemingly" operate in parallel mental universes and we therefore see "reality" very differently.

I think that the TPI graph represents an expert golfer who uses a pivot-driven swing action with optimum kinetic sequencing. It is certainly not a hand throw action that starts from the top of the swing. The left arm is moving at the same speed and rate of acceleration as the shoulders (rate of acceleration = slope of the graph) in the early downswing, because the power package remains intact in the early downswing. The left arm only eventually moves faster than the shoulders/hips in the mid-late downswing when the hips/shoulders decelerate due to natural forces - and that represents the release of PA#4.

You state-: "Thrust is the "Rate of the Acceleration" not the "Acceleration" (which is the rate of Velocity).

I disagree. In my mental universe, "acceleration" is the rate of change of velocity (change in velocity per unit time) and the slope-angle of the TPI graphs reflects the degree of "accleration". The phrase "rate of acceleration" only has meaning to me if the slope of the graph changes significantly in slope-angle during the acceleration phase of the downswing. That shouldn't happen in a good golfer - as reflected by those TPI graphs.

You write-: "The hips pull the Shoulders through the Impact Interval and beyond at a steady speed to provide an increase in Mass."

Where is your "evidence" that the hips and shoulders are moving at a steady speed through impact? You state a steady speed is required to increase "mass". What "mass"?

You write-: "The Clubhead should reach its maximum speed three feet after impact, or at least that’s what you should be trying to do. That's the #4 Accumulator."

I disagree. I agree that the clubhead should be reaching its maximum speed at impact (or just after impact) but that is not conceptually equivalent to the release of PA#4. Clubhead speed is dependent on the speed of release of PA#4 and PA#2, and it is also dependent on the principle of COAM. Increasing speed of the clubhead requires energy that is derived from the left upper limb in a swinger's action, and according to the principle of COAM the left arm must slow down when the clubhead speeds up (in the absence of additional energy input in the late downswing). I am not aware of any force that is inputting further energy into the moving left arm/clubshaft unit during the late downswing.

Jeff, I hope this reply finds you well. Obviously, you're confused. Concerning your last paragraph: If the Right Wrist remains Level and Bent throughout the Backstroke and Downstroke and leads the Club into impact, then how does the Uncocking Left Wrist Increase the Speed of the Clubhead greater than that which has already been provided by the Right Forearm? It's not a trick question.

You didn't need to go through all of that research just to find out that most pro's have hands decelerating before impact. You could've just asked me.

If you want to use the pro's for research in how to compete on tour, I'm all for it. But if you think that by studying the way the pro's swing that you'll uncover a secret, then good luck and when we meet on the other side, you can tell me all about it.

If you want to believe that the only way to swing is by dumping all of the energy on the ball at an impact location then go ahead. Impact is incidental. But explain why some golfers have the club twisted around their bodies at the end of their swing. Is that Fall-out?

6-M-0 GENERAL The Release triggers into action all the Power Accumulators employed in the Power Package and starts the Components toward their respective pre-selected Impact Positions. All practice is focused on mastery of this Moment of Truth. All Concentration is directed toward holding the attention to the requirements of the Total Motion during the Downstroke sequence – that it will flow smoothly through Impact from The Top directly to The Finish ( at least the Follow-through) without the slightest disturbance from – or for – Impact (12-13).

6-M-1 DOWNSTROKE SEQUENCE The Downstroke sequence of the Stroke Components is dictated essentially by Centrifugal Force; acceleration of a lagging Component will cease at the instant it achieves an “In-Line” position with its immediately preceding Component.

Centers and Accumulators can be sequenced, overlapped, omitted, emphasized, triggered, and timed as the players understanding and skill permit. But the Club’s Swing Radius (6-B-0) ends at the “non-lagging” Component nearest to the Clubhead. The “Centers” of the Stroke start with the Feet or the employed Component nearest to the feet in the following order: Knees, Hips, Shoulders, arms, Right Elbow, Left Wristcock and/or Left Hand Rotation. For maximum Power, the position of must be taken with that will allow Delay of the Release until all Components, except the Right Foot and Right Shoulder, have reached, or passed the Line-of-Site-to-the-Ball per 6-B-1-C. Then the Accumulators must move very rapidly toward their “In-Line” Position. But none should actually arrive (lose all their Lag and Drag until well after Impact. Also see 6-H-0.

Power Accumulators Release sequence is #4, #1, #2, #3 – regardless of which ones are being employed. Any Accumulator number may overlap or replace its preceding number but cannot precede it. Increase Overlap to increase THRUST – decrease Overlap to increase Velocity.

So Jeff, did he just say to blast the Left Arm off of the Chest at the Beginning of the Downstroke? Where is that? I must be misreading the Downstroke Sequence. I changed the text to red so that it won't take you too long to find it.

6-C-2-B ANGULAR ACCELERATION The Clubhead “overtaking” speed is governed by the Law of Conservation of Angular Momentum whereby the increased Mass resulting from any extension of the Swing Radius decelerates the hands and unless they are supported by Power Package Thrust (6-B-1) or Throw Out Action (2-K), can result in great loss of Clubhead Speed. Rely on Clubhead Lag to meter out the necessary support for the Primary Lever Assembly. Strictly speaking, any increase in the product of Mass times Velocity is Acceleration whether or not the Speed is changed. But the formula for Kinetic Energy gives Velocity the greater value. And, actually, the acceptable tolerance in the Ball-to-Clubhead weight ratio is quite small.

And Lastly:

6-B-4-0 THE FORTH POWER ACCUMULATOR The angle formed by the Left Arm and Left Shoulder forms the Forth Power Accumulator. It is not only an independent Power Accumulator, but its Triggering function as the Checkrein of the Right Elbow is also vastly important and it thus can be the Accumulator of the Accumulators – or Master Accumulator. Also see 2-M-4.

As Accumulator #4 it is Pivot (Body) Power supplying the initial acceleration of the Downstroke to throw the Lever Assemblies toward Impact by the Thrust of the Shoulder Turn. See 7-13. Another major contribution to Impact Power is geometric – it is the first link in the Swing Radius power train between the Club and the Feet.

[B]“Left Arm Power” in any form or amount can still be considered #4 Accumulator Action.[/b] Otherwise it actually substitutes for the Pivot to introduce the circular motion required to produce Centrifugal Force.

Bold and Red by me. So, my ART stands the way I see it. Jeff, for anyone who wants to copy my art, it's only 5 cents, but for you, it's 10 cents.

I have no idea what you are talking about!

In a swinger, the club release phenomenon occurs passively due a centrifugal action (law of the flail - law of the double pendulum swing model). The right forearm does not apply any swing power or actively influence the club release action.

You write-: "So Jeff, did he just say to blast the Left Arm off of the Chest at the Beginning of the Downstroke? Where is that? I must be misreading the Downstroke Sequence. I changed the text to red so that it won't take you too long to find it."

I never stated that the left arm must be blasted off the chest wall at the beginning of the downswing. I stated that the left arm gets passively blasted off the chest wall when the pivot action subsides and that usually happens in the mid-downswing.

Here is a video of Hogan's PA#4 release - note at what point in the downswing Hogan's left arm starts to move away from his chest wall.

Here is a more precise rendition of the timing of Hogan's PA#4 release.



It is my opinion that Hogan's PA#4 is being released in the yellow colored zone (image 2).

Jeff.

#3 strives to be MAINTAINED thru impact.

#2 is zeroed out when the wrist has been FULLY UNCOCKED.

#3 angle is arrived at when the wrist is in it's LEVEL condition and that angle is strived to be rolled through impact to avoid a plane shift.

#4 is fully released when the angle between the left arm and left shoulder is 90 degrees.
