Personally,

As a small apprentice point of view.

There are 2 points i like to say.

1)Stationary head of course is the Uncompensated Version of the pivot, As long as the width caused by the bent right wrist, shoulder height position during impact head position is constant, its a more or less "perfect" impact.

2) I feel, the head a shy behind the center , swivels, and thus slight bobbing is more biomechanical and comfort, ie the head bending forward instead of proudly straight, bend forward spine, other things like trying to coil the torso, the concious or unconcious need to feel positive weight and momentum transfer, such and such, either can be merely a matter of what you want to feel. Most of this type of head position will in evitably need to bob slightly to the correct impact alignments for a solid impact, or make other compensation. But it does not mean its wrong. alot of great legends does that.

And I think its an acceptable preference and compensation. though I feel its still compensating. you do not need to do that as the less movement in golf is efficiency.

Just my tiny 2 cents.
