TURNED SHOULDER PLANE:

The #4 Accumulator is Loaded as the Right Elbow Bends and the Left Arm is carried across the Chest. The load location is where the left arm pushes against the chest. On a Turned Shoulder Plane, the #3 PP, #2 PP and Right Shoulder are ON PLANE. As the Downstroke begins, the #3 PP, #2 PP and Right Shoulder remain ON PLANE. The Pressure (Force) from the #4 Pressure Point is ON PLANE. As the Shoulder Turn subsides, this Pressure Blasts the Left Arm away from the Chest and the #2 & 3 Pressure Points are Blasted toward the Aiming Point and CF begins to Pull on the Clubhead Sweet-spot (Throwout).

So, the Unloading Force of the #4 PP is ON PLANE with the Right Shoulder and #2 & 3 Pressure Points.

The #4 Accumulator Load, is fully spent when the Right Arm is fully Straight (both arms straight). How far past Impact the Follow Through ends is a matter of Shoulder orientation.

When on the ELBOW Plane, things are very different. Rather than the #2 & 3 Pressure Points and Right Shoulder moving On Plane, they drop vertically toward a point somewhere between the feet and the plane line. This is not On Plane. This vertical drop lowers the Hands to the Elbow Plane. The Left Arm does not move Away from the Chest.

For Elbow Plane Swingers, the #4 Pressure Point becomes disengaged during the initial Vertical Drop from the end of the Backstroke undoing its potential PRIOR TO RELEASE. While for TSP Swingers, the Left Arm Blasting Off of the Chest is the Beginning of Release and adds an almost unmeasurable amount of Power.

Hitting a 7 iron 190 yards is a pretty simple undertaking and a great test to evaluate the power and "How Well you use the #4 Pressure Point". The 7 iron is short enough to accelerate very fast and has enough loft to trim to a respectable 6 iron and COAM isn't a problem. The Driver , on the other hand, is very long and the COAM effect requires an enormous amount of muscle or Power Package support to overcome.

The Clubhead “overtaking” speed is governed by the Law of Conservation of Angular Momentum whereby the increased Mass resulting from any extension of the Swing Radius decelerates the hands and unless they are supported by Power Package Thrust (6-B-1) or Throw Out Action (2-K), can result in great loss of Clubhead Speed.
