Extensor action simplifies Rhythm IMO.

As Homer would say, Ed..."Kee-rect!"

Rhythm in The Golfing Machine is defined as maintaining the In-Line condition of the Left Arm and Club (Primary Lever Assembly) during the Impact Interval (6-B-3-0). The Flat Left Wrist directly controls this Rhythm by executing one of the three Hinge Actions (2-G). This, in turn, determines the unique degree of Clubhead Travel and Clubface Closing from Impact to the end of the Follow-Through (Both Arms Straight).

However, despite this veneer control of the Flat Left Wrist and its Hinge Action (2-G), it is the straightening Right Elbow -- driven Centrifugally (Swinging) or Muscularly (Hitting) -- that actuates the Roll of the Primary Lever Assembly (Left Arm and Club) through Impact. That being the case, the Right Elbow's Location during Impact will directly and dramatically affect:

1. The amount of Clubhead Travel;

2. The degree of Clubface Closing; and thereby

3. The Rhythm of the Stroke.

There are many things that can disrupt the Right Elbow Location pre-selected at Impact Fix. Among the most important of these is the lack of Extensor Action. Unless the Right Arm is kept constantly stretched, it can stretch at any time, and this 'wobble' factor can be highly disruptive.

But with Extensor Action applied, the Right Arm can straighten only as the Left Arm moves away from the Right Shoulder (6-B-1-0). This produces a smooth, unbroken Acceleration of the Lever Assemblies (6-A-2/3); a consistent Right Elbow Location; and, hence, the correct amount of Clubhead Travel and degree of Clubface Closing throughout the Impact Interval (6-B-1-D #3).

All this is Rhythm...the Third Essential of The Golfing Machine (2-0).
