Yodeli ,Spike. These are great points. Focus is pressure point awareness, then. Maybe.
Force is applied to the ball through the Lever Assemblies. Power is applied to the Lever Assembly through the pressure points. Pressure points 1,2,3 are on the aft of the grip. Its these pressure points that we swing on plane and towards the plane line. Mind in the hands is really mind on the pressure points.
Clubhead control is lag pressure point control. Clubhead force is proportional to speed, mass and the width of the swing radius. A sudden slackening in the radius will lessen the force and deaden the pressure points. Extensor action is a substitute for arm acceleration.
