How do you interpret the following statement at the end of the second paragraph under 6-B-0?
"So, the Clubhead (or primary Lever Assembly) whose Swing Radius extends to the feet is much harder to decelerate during Impact, which means better Clubhead Speed at Separation."

It's that stuff we were trying to get you to consider in the other thread about the extension of the spine in the longest hitters . . . .
Imagine three golfers who each generate a clubhead speed at the time of first ball contact of 100mph. They each swing an identical driver that has the same clubhead mass.
1) Golfer A is a swinger and he simply uses a 4:2:3 PA release action. His clubhead reaches impact due to the passive release of PA#2. His clubhead obviously decelerates during impact.
2) Golfer B is also a swinger and he also uses a 4:2:3 PA release action. However, in his "mind" he envisages that the swing radius of his clubhead arc extends to his feet (whatever that mental concept entails). His clubhead obviously decelerates during impact.
3) Golfer C is a hitter and he powers his swing via the release of PAs 1,2,3. His clubhead obviously decelerates during impact.
Do you think that there is any difference in the magnitude of clubhead speed at the time of ball-clubface separation between the three golfers, and do you think that there is any difference in ball velocity between the three golfers?
Please support your opinion with a sufficiently detailed explanation.
Its been gone over a million times but in essence Mike down under is right.... Even if the shaft weren't relatively speaking "a noodle" making it virtually impossible to transfer any appreciable force to the club head during impact, the time duration is so small that the force has practically NO EFFECT
V = velocity = integral of Acceleration (this is basic calculus)
V = A dt .... where A is acceleration (force divided by ball mass)
where dt is the time the force is in effect (i.e. during clubface contact which is .0005 seconds max)
This is why I asked soulmanz what kind of force he thought he was capable of generating. It figures he being a know-nothing poser would not answer.
But lets say for argument sake the shaft is infinitely stiff (doesn't deflect under applied loads) and lets say and the golfer (your "hitter") could put 10 lbf into effort on during impact (totally unrealistic situation but just for the sake of argument of it lets assume its possible) Then how much additional velocity would a hitter's effort give the ball?
He-man hitter picks up maybe 1.09 mph which ain't squat. Better to focus on proper technique then to subscribe to a debunked theory of the "heavy hit".
I interpret nmgolfer's post as indicating that golfer C would not generate a significantly greater ball velocity than golfer A, and that golfer C's clubhead will not slow significantly less than golfer A's clubhead as a result of ball collision.
What about golfer B compared to golfer A? What does HK mean when he envisages a swing radius extending from the feet to the clubhead, and what effect does this "mental construct" have on ball velocity and clubhead slowing as a result of ball collision?

That quote is about pivot lag not really about the release sequence or power accumulators . . . . each pivot segment lagging and getting in line. I'm quite sure that Mandrin is aware of "snapping the chain" or whatever they call that deal. I think that's what Homer was on to there. Again . . . . the longest hitters tend to have spines that are very extended.
Swinging from the feet and pivot lag is what he's talking about there.
6-M-1 DOWNSTROKE SEQUENCE The Downstroke sequence of the Stroke Components is dictated essentially by Centrifugal Force; acceleration of a lagging Componet 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 employeed 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.

Where are you getting "mental construct"? That's your words not Homer's . . .. He's talking about pivot lag . . . not some kinda concept deal. You either got components lagging from the feet . . . or somewhere further up the pivot chain . . . . that's what makes the difference . . . . lag in the pivot works . . . lag in the brain or lag in the construct . . . not sure about those.
