Here is the exact quote:
"The Lever Assembly is seldom more then an inch from Full Extension at Impact".
Agreed, Mike: There is a difference between my conclusion (point of Full Extension past Impact) and the "exact [Kelley] quote" (degree of Extension at Impact). For practical purposes, I believe that my conclusion is valid.
Remember, the Left Wrist doesn't go from Cocked to Level -- then hang around a while -- and later proceed to its Uncocked condition. No sir, the Left Wrist is rapidly Uncocking -- perpendicular Wrist MOTION (4-0 / 4-B) -- and it is Releasing in one unbroken thrust. Even with the Swinger's Sequenced Release (4-D-0), there is an overlapping of the #3 Accumulator Wrist Roll and completion of the #2 Accumulator Wrist Uncocking.
In any event, the Left Wrist ideally is Level at Impact and then immediately proceeds down approximately one inch to fully-Uncocked through the Impact interval. No way does this complete Uncocking take until the end of the Follow-Through (which was Jeff's point).

I don't want to get too far from the subject of this thread, but since you've raised the question . . .
If at Impact, the Primary Lever has only one inch to go until it reaches Full Extension, and if the Left Wrist is Releasing freely, then what is your best guess as to when Full Extension occurs, i.e., how far past Impact?

Whenever the #3 accumulator becomes the smallest.

If you started with a small enough number 3 accumulator where you could make it to zero, via the uncocking motion. Otherwise, based on the grip taken maximum extension would be maximum uncocking regardless of whether you made it to zero #3 or not.

Would this be a maximum #3? If so, what does this imply? And what if you were older and couldn't zero it because of an arthritic condition? Would this eliminate the #2 accumulator? How about #3? I see no reason for that because clearly Moe Norman never did either. For example, consider http://perfectgolfswingreview.net/swingplane.htm. It doesn't come close to the breadth of my argument, but you get the idea. Plus, if you'll draw the lines -- I see no need to go to that extreme here since it is obvious and everybody can see it -- you'll see that his head moved at least .0001 of an inch (in front of the ball . . . but that is in a different place than Ben Hogan's or Jack Nicklaus's ball). BTW, is that right? You know, should it be Nicklaus's or should it be just Nicklaus'?
Finally, would any of this affect my ability to pivot Saturday night at Hernando's Hideaway?
Please don't delay your post . . . "I gotsta know."
P.S. Jeff, please don't take offense, you know "I luv ya, man!" And sincerely appreciate all you are doing here. It's just that sometimes . . . it can get to be a bit much. But that's you, and I'm growing fond of your deep-digging. Keep it coming, my friend; just know that there are time constraints on my ability to read your insightful posts, let alone comprehend and respond.

Sorry Lynn but I can't answer you - I just started drinking myself. By the way, in post 32 you said that both eyes, the nose and my left wrist should be in-line and centered over my navel- please explain?

Here is a simple thought experiment as to whether Tiger's driver clubhead arc should be elliptical or perfectly circular in shape, and whether two consecutive driver swings would have clubhead arcs of exactly the same elliptical shape.
To make the experiment simple, consider that the pivot center (base of the neck at C7) remains fixed in space during the downswing between swing A and swing B. Also accept that the clubhead is in exactly the same identical 3-D position at the start of the downswing in those two swings.
Now consider what factors will affect the position of the clubhead in space at different time points during the downswing. Imagine a very accurate timer that can measure the downswing action in millionths of a second, and let's determine where the clubhead will likely be located after xx/100th of a second into the downswing.
There are six interacting variables that will influence the clubhead position after xx/100th of a second.
1) The speed of rotation of the left shoulder socket around the "fixed" pivot center.
2) The exact angle of rotation of the left shoulder socket around the "fixed" pivot center. For example, in swing A the left shoulder may rotate around the pivot center at a 90 degree angle while in swing B it could be at an 85 degree angle.
3) The speed/timing of left arm rotational movement around its left shoulder socket fulcrum point which depends on the PA#4 release pattern.
4) The angle of the left arm's rotational circle relative to the left shoulder socket - relative to the inclined plane.
5) The precise timing of release of the clubshaft (uncocking of the left wrist) and therefore the precise timing of the lengthening of the left arm-clubshaft radius.
6) The angle of the clubshaft release relative to the back of the left hand. Hopefully, the left wrist will uncock perfectly in plane with the left arm so that the clubshaft will release in the same planar arc of the flat left hand, but there could be a variation of a few degrees from swing-to-swing.
One doesn't have to be a rocket scientist to realize i) that the 3-D clubhead position at xx/100th of a second will not likely be in the same precise 3-D location in swing A compared to swing B; ii) that the total clubhead arc shape will more likely be elliptical in shape rather than perfectly circular in shape; iii) that there is no fixed center of an elliptical arc; iv) that there is no necessary causal reason why the pivot center (base of the neck) should be at the "center" of that elliptical-shaped clubhead arc.
It also doesn't require a rocket scientist to realize that the i) low point of that elliptical clubhead arc may be just inside the left foot, or somewhere else - dependent on the "fixed" position of the pivot center; and that if the low point is just inside the left foot that it doesn't necessarily imply from a causal perspective that the pivot center must be in the center of the stance.
