Having thought of this only because of personal experience (same problem), it really, really sounds like you are coming into impact over plane.
Related, as far as what to think about, ultimately, think of driving (swing - passively, hit - actively) down and out toward the plane. Because of your already installed hinge assembly (and preprogrammed Type of hinge assembly), hinging will occur as a result of thrust to the plane line. The tremendous momentum from these actions will necessitate that a finish swivel occurs. Now, actively causing, or actively monitering a finish swivel, for a period of time, might help the actions preceding the swivel (preceding actions will be "forced into place").

Think of a door. There is no need to think of hinging. The hinge assembly is already installed. All you have to do is push (drive the door). All "timing" - when the door will line up with the frame - is taken care of by the hinge assembly.

As far as over plane driving, focus on eliminating clubhead throwaway by establishing, producing and maintaining clubhead lag pressure (Clubhead feel). If you lose clubhead feel, you will have throw away.

I'm not sure of what you mean by "over plane"; is that the same as "above
plane"? or you mean I'm reaching out with the clubhead beyond the plane
line?

Wait a minute...what am I supposed to push? I think only of pulling with my
left arm.

Anyway I thank you so much for all your precious infos.
