"6-G-0 HAND MOTION All motion is focused on driving the Hands - NOT THE CLUB - toward the BALL. This may, with habit, seem to be come reversed. But this is where and hwo a player's game "comes apart." And the cure is to return to the original primary concern - the Hands and their Clubhead Lag, Wrist Positions and "On Plane." The On Plane relationship of the Hands, Shoulder Turn, and Hip Turn causes them to feel and look (to the player) as though they were all travelling parallel with the Plane Line from Top to Finish. Having a geometrical basis, this "Parallel Pivot" is acceptable therapy for the tendency of any or all of of the three motions to lift the clubhead "Above" Plane and set up Pull Shot alignments. (see 7-13.) On Line Hand Motion can compensate for Off Line Hip and Shoulder Motion but only up to a point. Off Plane Clubhead Throwaway is even a very prevalent Putting and Chipping Fault. It amounts to an unintentional Plane Line shift and causes direction control to become vague and erratic. So, learn to hit the ball with Hand manipulation rather than Clubhead manipulation and your game is much less likely to keep falling apart."

In 1969, after 28 years of research, Homer Kelley decided to publish his findings in book form. He organized and wrote The Golfing Machine in the format and style he had learned writing technical manuals for the U.S. Navy, but even so, he at first wasn't terribly concerned where the information appeared. In his final lecture -- delivered the day he died (February 14, 1983) to the Georgia Section PGA in Macon, Georgia -- he said that his main goal early on was simply to "get it down." His great fear was that he would not live to complete "the project" and that it would be "another 700 years" before somebody would come along who could "solve the problem." He had a strong sense that millions of golfers were looking over his shoulder saying "Don't blow it...don't blow it."

As the editions evolved, he became more and more concerned about putting each piece of information in its most logical place. And he felt the "Parallel Pivot" concept was best placed with the Pivot Component in 7-12, not in the Hand Motion discussion of 6-G-0. Also, as his thoughts crystalized on Swingers and Hitters and their respective Delivery Lines (Arc of Approach versus Angle of Approach), he wanted to differentiate the parallel motion necessary for each. Hence, he eliminated the above bolded sentences in 6-G-0 and replaced them with the following in 7-12:

"ALL motion -- Pivot and Power Package -- moves parallel to the selected Delivery Line. That is, prior to the Downstroke Turn, a Slide parallel with either the Angle of Approach or the Plane Line per 2-J-3."

Personally, I feel both quotes provide unique insights, and that is why I study all the editions, not just the 6th.
