Again, where is the pivot point in pitch In regards to recent question about neutral point, as being defined as center of lifts from wing and tail, could one also define a "neutral point" for down forces CG AND down force (up elevator) from tail.
Lift force is now only from wing

Notice if the down force center is behind the lift center, the nose pitches up.  Would the center of this rotation be at the wing, at the center of all moments (between Clift and Cdown), or somewhere else?
Disclaimer:  I am no expert and if you get a better answer from one of the other contributors here, you should listen to them, not me.

From what I can tell, it looks like you're asking whether you can define a point that includes all downward forces on the airplane, including center of gravity and tail downforce.  As I understand it, yes you can, and this point is center of gravity, which includes all the associated downward forces.

The airplane then would pitch about the center of gravity, as it usually does.
