stick to your guns , you were right .
There is little doubt that in many golfers who have a "late release"/"accumulator lag"/"trigger delay", they have a LOW left shoulder late in the swing.
For many of the same reasons that a "reverse pivot" will produce less "late release"/"accumulator lag"/"trigger delay," a left shoulder moving up to soon can do the same.
In some the best swings, axis tilt does not occur until late in the downswing!
SERGIO does tilt the axis and move his right shoulder down at start down and his left shoulder up, even though ( frame 5 ) his arms and hands have traveled farther. remember the start down is the period of shoulder acceleration and the downstroke is the period of hand acceleration.
since the right shoulder is closer to the center of the clubhead orbit and the hands are closer to the perimeter, the hands must travel a greater distance in the same amount of time so the accumulators must be released to achieve proper impact alignments . due to this accumulator #4 starts to release and the the right shoulder must stay back and on plane for an on plane centered motion.(the centered motion as well keeps the right shoulder from moving very much DOWN AND FOWARD through his entire stroke.)
god, i sound so golfing machine !!!! i can’t help it, i just love abstraction and preferably sheer abstraction !
it's a shame his coach wants him to "flatten out his plane or the shaft" (frame 4) or whatever ”the great players do.”
and get off plane(frame 4 & 5) in his downstroke, along with float loading ?!!!
it’s a shame his coach ( perhaps i’m being unfair to his coach? ) doesn’t want him to take his right shoulder shoulder, hands ,clubshaft and clubhead ALL DOWNPLANE. as it is his hands and clubshaft are UNDER PLANE and he now has to “swing left” with his hands and arms ( rather than swinging left with his hips and shoulders first ( concentric circles mr. o’grady ?) ) and what appears to be angled hinging ( instead of horizontal hinging ) and then ABOVE PLANE ( instead of ON PLANE ) near finish (frame 7) .
his hands and arms are working real hard to try and maintain alignments !
it's too bad this kid does not have a good instructor. he is so loaded ( no pun intended ) with talent, if you could get him on a better plane he could win a lot of majors .
treating a complex action as complex can ultimately make it simple !!
