Wouldn't a pushing action of the #2PP against the club grip cause this left arm extensor condition?
No, Spike, the #1 Pressure Point (the Heel of the Right Hand against the Left Hand thumb) applies the Extensor Action of the Right Triceps to stretch the Left Arm. Otherwise, the Left Triceps (no pressure point) is responsible for straightening the Left Elbow.
Other than normal Grip Pressure, the #2 Pressure Point (the last three fingers of the Left Hand) actuates the Secondary Lever Assembly (the Golf Club) only by Centrifugal Force (as passive Clubhead Lag per 10-11-0-2).
