It's actually "Sustain the resistance ("lag") encountered during shoulder rotation".
That's pretty much right!! Imperatives and essentials are the "effect" "caused" by "sustain the lag through shoulder rotation".
One last shot: you do the "cause" and the "effect" shows.
Wow what a BOLD STATEMENT...I guess most of us on the forum have been wasting our time going through "much ado about nothing".
But wait a sec...per 5-0
"The alternative to Hand Controlled Pivot is, of course, Pivot Controlled Hands, per 10-24-F. That does not alter the Basic Geometry or Physics requirements, but assigns to Physics precedence over Geometry - Force dictating alignments. Which obviously reduces precision; but,also Clubhead Throwaway. The information for such procedure is all included herein - merely Monitor the Pivot instead of the Hands.
That is, primarily, the use of The Shoulder Turn Takeaway instead of Right Forearm Takeaway. But that procedure is so inferior that detailed consideration does not appear warranted except in a transitional undertaking.
However, if the Clubhead is Monitored directly instead of through the Hands, it is, as always, a chronic disaster. If the Hands are Monitored, Pivot Controlled Hands vanish."
