I have no problem with Yodasluke backswing for the sweet spot to be off the sweetspot plane for it is during a low energy stage. Yodasluke's plane maintenance is amazing to me and I will try to copy that in my never-ending swing revision.

On the downswing, the clubhead behaves exactly as predicted by Newton's Laws.

What I take from the swing is that at the vicinity of impact, the center of the centripetal pull or the center of your so called instantaneous curvature lies near pp#4 that is Yodasluke in counterbalancing the enormous dynamic weight of the clubhead with his torso or the whole body-- he must. If that is the case then, I have no qualm for pp#2 not on the sweetspot plane.
