Ben Hogan, speaking of the Left hand grip in Five Lessons:
“In the completed grip, the main pressure points are the last three fingers, with the forefinger and the palm pad adding assisting pressure.
The three fingers press up, the pad presses down, and the shaft is locked in between.
Keeping pressure on the shaft with the palm pad does three things:
1. It strengthens the left arm throughout the swing;
2. At the top of the backswing, the pressure from this pad prevents the club from slipping from the player’s grasp; and
3. It acts as a firm reinforcement at impact.
This pressure we are speaking of should be “active,” the kind of pressure that makes your hand feel alive and ready for action.”

In his last sentence Ben appears to be differentiating between a “passive” pressure exerted on the palm pad by some other means. Is he suggesting the last three fingers of the Left Hand?
If this “active” palm pad pressure is as important as Ben Hogan believed why did Homer not recognize it as a valid Pressure Point?

There are many 'points of pressure' in every Golfing Machine, but only those through which the Power Accumulators exert their force -- directly or indirectly -- are defined as Pressure Points.

In the Grip, for example, the left forefinger mentioned by Hogan certainly exerts a pressure (by the mere act of encircling the Clubshaft and applying its gripping pressure). The same could be said of the middle two fingers of the right hand. However, none of these 'points of pressure' drive the Left Wristcock (Power Accumulator #2), the Right Elbow Bend (Power Accumulator #1) or the Left Hand Turn and Roll (Power Accumulator #3). Therefore, they are not defined as Pressure Points for Power application.

In contrast, the last three fingers of the Left Hand constitute the Pressure Point application of the Left Wristcock Power. The pad of the hand cannot grip the Club by itself, nor can it actuate the Left Wristcock. Nevertheless, as Hogan noted, it is 'activated' by the gripping pressure of the fingers. Clench your fist, for example, and feel what happens.

The main point Hogan is making is that, in full Strokes, the Club Handle is best secured by gripping it under the heel pad. He lists three benefits, but misses perhaps the most important: namely, by placing the club under the heel of the Hand, you automatically create an angle between the Left Arm and Clubshaft. This Angle constitutes the #3 Power Accumulator with its Rotational Power and also, its three possible Hinge Actions (and their unique Rhythms).

For that reason, gripping the Club under the heel of the Hand is important for virtually all full-shot applications of Power. However, on short Shots, particularly Putts and Chips, the player may opt to place the Club Handle in the lifeline of the Left Hand (and therefore not under the pad), thereby eliminating the Left Arm / Clubshaft Angle (and its built-in Power). The last three fingers again provide the gripping security, but without the opposing assistance of the pad.

In any event, remember that the Hands serve as Clamps to secure the Club to the Machine. Once secured, the Grip (with its Pressure Point Pressures) serves to transmit On Plane Power -- Centrifugal (Swinging) or Muscular (Hitting) -- while controlling the Clubface alignment. All in compliance with the dictum of 1-L #3:

"There is no wobble in the Clubshaft Attachment (Grip)."
