[O.B.Left]

No. I do not believe that there is an axis of rotation between the left foot and the upper swing center.



I DO, ASSUMING THERE IS AXIS TILT. FOR NON SHIFTING STROKES THEN THE AXIS OF ROTATION IS CENTERED , ASSUMING THE HEAD OR CENTER IS CENTERED.



I think that the idea of a pivot axis is merely a mental construct imposed on a human being's 3-D torso movement in space during the downswing. In that sense - in the sense of a mental construct - it makes more sense to me to imagine why a person would imagine a "hypothetical" pivot axis between the upper swing center and the left foot rather than between the upper swing center and a point on the ground midway between the feet.


I THINK THAT AXIS TILT (WHICH REFERS TO THE SHOULDER AXIS) ALSO TILTS THE TORSO, ASSUMING THE CENTER IS HELD STEADY AND THEREFOR TILTS THE AXIS OF ROTATION OF THE PIVOT.



Either way, I don't personally find the mental construct of a pivot axis helpful. I simply cannot understand how this "mental construct" could help a golfer move his torso better in space.


KNOWLEDGE MUST BE WORTH SOMETHING. YOU OF ALL PEOPLE SHOULD ADMIT THIS. YOU BEING SO FAR FROM "GRIP AND RIP IT" PRACTICALITY.


I think that one merely needs to position one's head in a "desired' position at address, and then start the downswing with a hip shift-rotation movement that produces secondary axis tilt, that allows the right shoulder to move downplane. Then, by keeping the head stationary, the torso will spiral in a rotary manner towards impact, and beyond impact.

FINE ME TOO. I DESIRE IT TO BE CENTERED UNLESS I NEED TO DO SOMETHING SPECIAL THAT REQUIRES A SLIGHT COMPENSATION.


I don't understand why an upper swing center that is slightly right-of-center should predispose to a draw, or why it should be described as a compensated swing rather than an uncompensated swing.


ITS ALL ABOUT MANAGING LOW POINT VIS A VIS THE BALL POSITION. WHY POSITION YOUR HEAD BACK AND THEREFOR YOUR WEIGHT BACK WHEN YOU CAN JUST MOVE THE BALL FORWARD AND SWING IN BALANCE? THIS IS THE UNCOMPENSATED SWING. BALANCE MUST BE WORTH SOMETHING NO?
IT IS IN EVERY OTHER SPORT.


I have recently posted two driver swing sequences - Tiger Woods and Stuart Appleby - where the head/upper swing center is marginally behind the center of the stance.


MINOR COMPENSATIONS ARE OH SO COMMON. THIS IS SHOT MAKING. FOREGOING A MARGINAL AMOUNT OF BALANCE FOR AN ADVANTAGE OF SOME SORT, IN THIS CASE PROBABLY LAUNCH ANGLE. WHICH THEY COULD ARGUABLY ACCOMPLISH IN AN UNCOMPENSATED MANNER BY MOVING THE BALL MORE FORWARD VIS A VIS THEIR LEFT SHOULDER OR LOW POINT.



I cannot understand why their swings would be labeled "compensated" or "draw biased". I don't believe that a small amount of right-of-center positioning of the pivot stabiliser point should predispose to a draw - if the golfer can easily shift his lower body forward onto the lead leg during the downswing and avoid a "hanging back" problem.


THE DRAW OR PULL BIAS COMES WHEN THE LEFT SHOULDER OR LOW POINT MORE CLOSELY APPROACHES OR MOVES AFT OF THE BALL POSITION. IT GIVES THE CLUBFACE MORE TIME TO CLOSE AS THE CLUBHEAD APPROACHES ITS UP AND IN PATH POST LOW POINT. I THINK THIS IS HOW I USED TO HIT A HOOK WHEN I WAS 16 YEARS OLD ANYWAYS.




I think that a "hanging back" problem will only occur in a good golfer if the head is positioned very far right-of-center (where the golfer is overtly leaning to the right).


A GOOD GOLFER WOULD ONLY OVERTLY DO THIS FOR A SPECIAL SHOT , SAY A LONG DRIVE GUY TRYING TO LAUNCH IT SUPER HIGH , WITH LOW SPIN.

My comments above in caps.

We're going in circles. Lets hurry up and get to the debate about the flat left wrist.
