Long story short (and using TGM terms for the benefit of the many members engaged in that study), what happened was that Paul brought to the table a Strong Double Action Grip (10-2-D / Left Wristcocking Motion on the same line as the Right Wrist Bend) and, with John's help, learned to use his Pivot (10-12-A / Standard Action) to originate and control Clubhead Power (10-4-D / 4 Barrel). Along the way, he learned to use Angled Hinging (10-10-C / Right Palm Paddle Wheel Action and No Roll Feel) to control the Clubface Alignment through impact (or, as John would say, "No forearm rotation and knuckles up!").
