Seems like just speed. How can you add weight (mass) to the club when it's already moving ?
From the First Edition:
Quote:
2-M-1 BASIC POWER
......Mass is the total effective weight that is impinged on the ball and is the sum of the deadweight plus the sustaining or driving actions of the applied Thrust.
The effective swing radius by the time of the release also makes a different. That should correlate prety well with hand speed.
Increased swing radius increases the effective moment of inertia - which is one of the "effective mass" parts. The other being active power during ball contact. Both of those will be felt as a varying degree of shock and impact resistance in the hands.

I was trying to ask - does the pivot simply enable more speed or does it create the speed?
Im thinking it is primarily the "spin of the flywheel", the initial acceleration upon which the Arms build, magnify. Assuming a Swingers Drag Loading 6-M-1 Down Stroke Sequence. For Three Accumulator Hitters it is still there but less key.
I kinda think of it this way . . . the "geometry of the circle" radius is the left arm and club no? but the SWING radius comprises the power package AND PIVOT (and all its components) . . . so you speak of #2 . . . cocking and uncocking right? . . . . so think of your knees, hips and spine also as "#2" for lack of a better word . . . you are going from "cocked" knees to "uncocked" knees . . . hips spine etc . . . in addition to producing "maximium SWING radius" this also allows you to keep the "flywheel" spinning . . . try to turn your hips the most and keep your left knee "cocked" and your hip joints "cocked" . . . keeping that rotation up helps to maintain the power package alignments, lag pressure and pivot lag going thru the entire machine . . .
Hey Buck
I think our posts crossed mid air. Mine wasnt a rebuttal to yours by any means. The difference in them is interesting. Is 6-M-1 to your mind about rotation and extension then? How do you extend all those levers and not raise up the left shoulder? I can see 6-M-1 in a slide or a turn way but never thought about it as an extend thing before . Cool.

Oh sure . . . I knew you weren't rockin' no rebuttalz . . . .
Go stick your head in a door frame and pivot . . . do it slow and pay attention to what happens. Notice how your knees joints, hip joints and spine has to change from out of line to in line to pivot centered. Now do it slow and try to keep the joints FLEXED . . . you gotta do some contorted stuff to make it work. "Tilting the teacup" involves moving several joint segments to stay centered. Pay particular attention to what your hip joints and spine does. Nobody does a true double anchor on the backstroke. They right knee is unbending to an extent. That allows the hip to continue turning . . . vicey versy on the downstroke. But if you look at the Hogan sequence . . . notice the left knee . . . IT'S WHEN IT HAPPENS . . . you want it to straighten for sure . . . but if it straightens early (gets in line) then the hips are going to start turning at that point. But say you don't ever straighten it . . . hips will be limited in their range of motion to turn also the hips will not extend (get in line) . . . could get saggy kneed and goat hump to keep the club coming from in . . . or chase with your head ala the old dude in those pivots. Note how his hips have not gotten in line.
Note how this dude's hips have not extended fully . . . his spine is vertical (not bent to the side) . . . his head would be off the door frame . . . up away and forward. Compare the head alignment to Hogan and Hogan to Tiger . . . See what the pivot has done to the head and eye line . . . Hogan would have his eyeline pretty much parallel to the plane angle . . . old cat is pretty much looking as if he were standing up . . . Tiger parallel to plane line. Hogan is the model . . .
Compare to Hogan . . . his head would still be on the frame spine is bent to the side and hips joints extended and continued to turn. Compare to Tiger . . . extended hips and knees but head went backwards. Note how hogan has "released" his head too. Maybe some of that stems from Tiger having that goofy head up set up versus having his face down . . .but if we had the full sequence to compare you'd likely see Tigers left knee straighten early and then head start moving backwards. So you can imagine the implications on the clubface with that much speed . . . fleeting alignments . . . versus hogan who can continue to move the face at a uniform rate because he has kept up his rotation. Note how much farther forward Hogan's right shoulder is than Tigers . . .

Excellent Post Bucket.... Even though Tigers arm swing is more independent than Hogans, I think that your analysis is correct.
I was reading a little in 5 lessons the other day and the 2nd paragraph on page 107:
Quote:
THE DOWNSWING. The shoulders finally catch up with the Hips at the end of the swing.
As regards the legs, a great many golfers think that classical style prescribes that, at impact and throughout the follow-through, the left leg should be as straight as a stick. Definitely not. If you keep your left leg straight, you prohibit your hips from making their full turn and restrict the whole free flow of your body.
And Hogans car accident was much more severe than Tigers SUV accident.
