I believe that one's PERCEPTION of WHAT is POWERING a golf stroke may be, and often is different than what actually is the case, in the most efficient and powerful strokes. One may FEEL the whole thing with their HANDS, but we know there is much more going on. One may FEEL SOMETHING within ZONE 1, but that does not negate the contributions of ZONE 2, AND 3, whether the golfer is aware of them or not.
PIVOT LAG(6-C-O) is in there in the most efficient and powerful strokes. Try to stand on ice and strike a ball... you will see!!
