Not being the roundest ball in the golf bag, I will add the following...

If the base of the neck is the stationary point, why would you want or allow a 20 lb plus object (the head) above that center point to have movement?

From the base of the neck (cv7?) is about 4 to 5 inches away from the center point of the head (cv1/2).

Rotation of the head around the spine (you stationary base neck point) does not cause the either center point to move.

Swaying and bobbing would appear to be acceptable product of base of the neck stationary center point UNLESS it is said to be otherwise.

The definition of swaying would be head movement to either side (toward the target or away). I will admit I am having some difficulty with swaying and a stationary neck base center point becuase of the short distance apart, it is more that head leans over with the ear touching the shoulder.

The definition of bobbing would be the up and down motion of the head.

It seems that either of these movements will be disruptive to the golf stroke, be it just impacting balance or causing unnecessary movements to compensate for the location of this 20 plus lb object that is now dancing around.

So is it really acceptable to having the head swaying and bobbing with the base of the neck being the stationary center?

It seems to me that the if the head is only allowed to rotate and is identified as the stationary point, the base of the neck would remain stationary as well. It would just not be the end or top of the rotational axis.

This all assumes the understanding is that if the base of the neck is choosen as the stationary point, then it can not move per-se. But if it can move then in that case it would not comply with 1-L-1/2.
