I will define this 'performance' in the following way:

A. Best able to create and sustain lag pressure
B. Best able to 'draw' a straight plane line
C. Best able to control hinge action

Got it?

Ok.

Here is my OPINION:

I think creating and sustaining lag pressure is easier with the base of the neck.

I think staying or getting 'on top' (or behind, if you prefer) of the sweetspot with your #3 pressure point—as in Horizontal Hinging—is easier with the base of the neck.

I think performing ANGLED hinge action or vertical hinge action to be easier with the "through the head" center.

If you bend you plane line too much to the left as a rule, you will find it easier to NOT bend it left with the "base of the neck" center.

If you bend the plane line to the right as a rule, , you will find it easier to NOT bend it right with the "through the head" center.

What do ya'll think?

Later you asked for

I am looking for an answer of any mechanical validity of what happens to the PATTERN and what happens to the club in both methods and if there are any advantages to either.

Maybe I have missed something but I still don't understand that if you the stationary center as the Head, why you would not receive all the benefits you claim you have with the stationary neck?

Is there some position for the Head to be in other than inline with the neck that has this benefit?

I definitely see the value in using the base of the skull (the head) over the neck as you don't want this 20 plus lb object flopping around, disrupting your balance, your eye alignment, etc.

The head as a component isn't an active component, or at least isn't suppose to be, so for it have negative results, I would assume that it has become an active disruptive component.

Mechanically, Science, etc. all would support the supposition that anchoring (so to speak, maintaining a central position) at the ends is superior to anchoring away from the ends. It reduces or minimizes the potential for variations, wobbling, etc. while allowing rotational drive to achieve its maximum on a predictable path.
