The swinger's pp#3 in that example would be in more of a supportive role until the hands swivel into impact, when the full force of the clubhead lag pressure is against it.

Pressure point #3 senses thrust. If the thrust pressure stays the same throughout the swing, then the acceleration rate was constant (but velocity increases dramatically). Less pressure (thrust) produces lower acceleration rates, thus less clubhead velocity. Greater thrust at start-down (starting pressure)which remains constant produces greater clubhead velocity (if you can Sustain the pressure). Swingers who want to hit the ball off the planet should swing at 80% and train the pivot to develop greater pressure on #3 and keep that same pressure constant (acceleration) until the finish swivel.
