Thanks for replying.

If the power accumulator #4 is fully released at the "both arms straight" end-followthrough position, then is it correct to state that all power accumulators used in a swinger's action are fully released at the same time time point, even though the release sequence is 4/2/3?

Secondly, you stated a 90 degree angle. However, I presume that the angle depends on the degree of shoulder openess at impact. The more open one rotates the shoulders by impact, the less the angle.

Consider the following sequence of Hogan's swing - note that left arm-shoulder angle is <90 degrees at impact, and that it remains at that angle well into the finish phase of the swing.



Jeff.

Jeff . . . Good questions dude . . . It's simply the relationship of the arm and the shoulder joint. It doesn't matter really where the shoulder is "in space". Once the arm is directly under the shoulder it is "fully released." So you could have a stroke where you had no shoulder turn at all. Just simply #4 accumulator motion via the #1 accumulator (right elbow) and once it is 90 degrees it's released with the shoulder turn "zeroed out". The shoulder turn simply carries the #4 angle via turning into the #4 pressure point. So basically the arm moves up and down the chest. It can be driven by the shoulder turn or swinging the arm.

So in the 1st frame I would say that #4 is "fully released" in your sequence of Mr. Hogan above. #4 is considered the master accumulator because if the left arm doesn't move "down the chest" then none of the other accumulators can release. You'd swing literally over the top of the ball.

6-B-4-0 THE FORTH POWER ACCUMULATOR The angle formed by the Left Arm and Left Shoulder forms the Forth Power Accumulator. It is not only an independent Power Accumulator, but its Triggering function as the Checkrein of the Right Elbow is also vastly important and it thus can be the Accumulator of the Accumulators – or Master Accumulator. Also see 2-M-4.

As Accumulator #4 it is Pivot (Body) Power supplying the initial acceleration of the Downstroke to throw the Lever Assemblies toward Impact by the Thrust of the Shoulder Turn. See 7-13. Another major contribution to Impact Power is geometric – it is the first link in the Swing Radius power train between the Club and the Feet.

“Left Arm Power” in any form or amount can still be considered #4 Accumulator Action. Otherwise it actually substitutes for the Pivot to introduce the circular motion required to produce Centrifugal Force.

RADIUS POWER

6-B-4-A MAXIMUM POWER is obtained by using maximum On Plane Shoulder Turn Thrust against Pressure Point #4 per 7-19, and maximum Swing Radius (6-B-0).

6-B-4-B ZERO ACCUMULATION is either no Shoulder Turn or the use of Accumulator #1 alone for actuating the Primary Lever Assembly.

6-B-4-C MAXIMUM TRIGGER DELAY is achieved by using either the Standard or Delayed Pivot (to increase the Lag of the Downstroke Shoulder Turn) with a Snap Loading Action (per 7-19-3 and 10-22-C) followed by a Snap Release (10-24-E) with a Pitch

One fault people have (me for one) . . . is NOT RELEASING #4 down the chest rather "OUT" which basically moves the hands out away from the plane rather than keeping them "in on-plane." Thus a compensatory move must be made because the radius (left shoulder to clubhead to ball) has been disrupted a miriad of compensations have to be made to get the sweetspot on the ball (standing up, flip, alligator arms . . etc. etc.).

But back to the sequence you put up . . . I think the #4 angle releases differently for different plane angles and hand paths. In other words, Hogan's pivot and plane is going to have the left arm "pinned" via the pressure point longer than say a Jack Nicklaus or Scott Hoch. Some one with lots of #3 angle that swings on a "wider" arc of approach (or just arc) is going to have #4 pressure point "pinned" by the pivot due to the hand path requirements, pivot requirements . . . to stay ON THE SELECTED PLANE.
