It meters out Power by sensing Clubhead Acceleration Rate and Direction. That is: To vary the Effective Clubhead Mass, vary 1. The Acceleration Rate (Lag Pressure 7-11) 2. The Swing Radius (length of the Primary Lever Assembly 6-B-0) The above quote, HK explains the "Physics" behind the concept of "How to vary the Effective Clubhead Mass" of the Clubhead. Maybe you need the "Laymans" explanation? See Below. Quote: 2-M-2 POWER REGULATION Clubhead Lag Pressure Point pressure (6-C) is the Power Regulator.
