6-C-1 PRESSURE POINTS The force to be applied for the movement of the Lever Assemblies -- both ways (opposite pressures 6-B-1-D) -- is exerted against the Club (7-11) through Pressure Points -- of which there are four:Here's the #1 and #3 Pressure Points
1. The heel of the Right Hand where it touches either the Left Hand thumb or the Clubshaft (as required by the Grip used.)
2. The last three fingers of the left hand.
3. The first joint of the Right Hand index finger where it touches the Clubshaft.
4. Wherever the straight Left Arm contacts the Left side
And here's the #4 Pressure Point.
The #4 Pressure point is different from the #4 Power Accumulator. The #4 pressure point is where the 'pressure' is between the left arm and left side connection. The #4 Power accumulator deals with the angle going from an acute angle to an obtuse angle as shown above.
A golfer can use any single pressure point or any combination of pressure points. 'Swingers' (left side pulling golf swing) primarily use the #2 and #4 Pressure Points. 'Hitters' primarily use the #1 and #3 Pressure Points. I suggest golfers really look into these pressure points. Before reading 'The Golfing Machine' I never utilized the #1 Pressure Point and since I have I've seen a little more increase in clubhead lag. I would imagine that many golfers are in the same boat. Or if you're a golfer that utilizes a 'swinging' technique, you may want to focus a little more on the #2 or #4 Pressure Points.
