[Yoda]

Do you think that Homer would change his mind on this subject in later editions if he was still around???.

The Golfing Machine® as we know it was the labor of genius for forty-two years.

The Stationary Head as the Pivot Center was a bedrock point from which that genius never varied.

So, do I think Homer Kelley would have switched to a Non-Centered Pivot over the last twenty years?

No.

In fact, he codified the Pivot Center concept in the as-yet-unpublished 7th edition as the Pivot Swing Center Tripod.

Do I think he would have embraced a different Pivot Center?

No.

Remember, his primary reference during the early years was Ben Hogan's Power Golf, the very same text from which photos have been extracted to build a case for the 'between the shoulders' Pivot Center.

Would he have changed his mind had he found evidence to the contrary?

Absolutely he would have.

But then again, in more than forty years...

He didn't.
