Some background on the editions.

Like so many golfing machine concepts, rhythm is hard to grasp not only because Homer used a word that has an intuitive meaning to most people, but also because the importance and precision of Homer's definition doesn't resonate with most people...until it is distilled and explained by great teachers.

He didn't fully define rhythm or mention it(I haven't found any use of the word) until the 4th edition. The development of the concept was important in describing accumulator #3 (6-B-3-0) The Third Power Accumulator - Roll Power.

Starting with 4th edition, Homer expanded 2-P to include the concept of rhythm when describing the function of wristcock. The term wasn't included in prior editions in this context. He also added the "golfers flail" sketches in 2K. Likewise, the Homer hadn't fully developed the concept of the physics of Hinging until the 4th edition in 2-G.

In the 4th edition he also expanded 2-G, the physics of hinging for hitting and swinging was that, "Roll is actually imparted by the turning torso and/or the orbiting arms per 2-K4 and 2-K5...The point to be learned here is that the Club, because of the Flat Left Wrist, must always travel at the same RPM as the Arms and reproduce the Hinging inherent in the selected Lag Loading procedure (10-19) per 4-D, 9-2, and 9-3, regardless of Clubhead Extention velocity. This is the basis of Golf Stroke Rhythm". In the 5th edition he removed the last sentence and replaced it with "See 2-P".

Thanks for the reply Bernt. I'll reread your earlier post and try to reconcile it. You're probably on to something.
