This illustration depicts the Swingers Release Sequence and Accumulator Overlap. Notice that the #3 Roll starts and ends within the #2 release travel and that the #2 release travel occurs within the #4 Release travel.
You lost me on the diagrams. Need more lableling I guess. What is that quarter (90 degree) circle at Homeplate? Is that the new Yankee Stadium on the right (more room on the third base side for A-rod's ego)?

That quarter circle is the Golfers Left Shoulder......
It's "Art". Did Pablo Diego José Francisco de Paula Juan Nepomuceno María de los Remedios Cipriano de la Santísima Trinidad Ruiz y Picasso use labels?
This is looking down on the golfer from above. The big black circle is your head. The little one is the Ball. The blue arc is #4 Acc travel. The red arc, #2 and the green arc #3.
The dashed line is your head looking at the ball. It's the line of sight to the ball.
The Black thin angled line is your left arm and clubshaft at impact.
I did this because we're always saying how the accumulators release in order, yet we rarely talk about that they occur within each other. #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.
Did not the Artist capture the reality of its simplicity in merely a few colored lines?
This painting sold for 95 million dollars, three years ago. And I used THE SAME COLORS.
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.
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.
