Yoda - I drew the yellow line exactly as HK specified in that sentence - between the top of the stationary head and a point on the ground precisely between the feet.
As stated in several of my prior posts, the Pivot Hinge Pin is presumed vertical to the ground.
"G.O.L.F. is a game for thinkers, and as detailed as this book is, it is still geatly dependent on thinking players" (1-G).
If the stationary head must be precisely centralized between the feet, and the hinge pin for the pivot center's rotation must be a vertical line drawn from the top of the stationary head to the ground, then the hinge pin line will simply be a vertical line drawn precisely between the feet with the pivot center located on that line at address.
That's why I think that most golfers (like Tiger Woods) do not have a pivot center in their swing.

Do you read at all? Or do you just write? Or do you just like to argue?
Have you even bothered to look at your own 'Big Three'?

Assuming you may actually be interested in words other than your own, read my post #16 -- learn something -- and stop tilting at windmills.

P.S. I don't know about the rest of you guys, but I'm all of sudden missin' DG!

Your looking at his driver swing, I believe. His iron swing is more balanced, centered if you will. No wobble at the top.
The premise of the book is that it is a machine, a golfing machine that we are trying to build. It doesnt take much to see the need for balance and a vertical c.o.g line about which to rotate. Like the spinning top.
Now if you did have a machine that wobbled about at its top, which of the following would you prescribe in an effort to increase its efficiency:
- More securely set its moorings to the floor in effort to stabilize it. Albeit with the knowledge that the wobble will still make for some inefficiencies, abnormal wear and tear, production delays etc etc.
-Leave it to wobble around on the floor. See the Creamer, Gulbis machines and how they wobble about at their connection points to the floor at impact. (They are both on their toes).
-Balance the machine so there is no wobble at the top and then for good measure secure it to the floor anyways (with some custom Maxwell golf shoes from England perhaps).
