I made Zone 1 changes over the summer partly because of this thread and partly because I’m compulsive-obsessive and if a little change is good, then more change is better.

I haven’t bought into “Biomechanics” training. Biomechanics has latched onto the idea that your swing will improve if properly trained to manage ground forces using leg muscles and joints. They may have studied human motion in every major sport. They help jumpers jump. They helped runners run. When in doubt, add more muscle.


Biomechanics Researcher: “How hard do you push with your right leg during the downswing?”
Golfer: “Not too much.”
Biomechanics Researcher: Push Harder.

About mid season I was sold on changing my pivot to include a defined “Sit-Down” Action. That became a train wreck. All that did was force my hands to an elbow plane during the down stroke. Anything that affects that straight-line delivery path does no good for my swing.
It’s not about the legs. Feet and knees accommodate Hip Motion. Hip Action moves the Shoulders.

My legs are "Passive" again. I use my feet and knees. They respond and allow. My head is stationary.

2-M-2 POWER REGULATION Clubhead Lag Pressure Point pressure (6-C) is the Power Regulator. 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)
To vary Clubhead Speed, vary
3. Acceleration Time (Length of the Stroke 10-21)
4. The Release Interval (Centrifugal Reaction 6-N-0)
So it is optional to use any one or any combination of the four alternatives. Also study 12-0 in this connection.
