THS and elevator position
@Gorry:
You are homing in on a theory several of us have expoused.
The Airbus stabilizer and elevators are "conventional". i.e. no all moving stabilizer as all military fighters have had since early 1950's. So your question is a good one.
Besides that, nobody here has yet to explain how the THS moves with respect to stick commands. I am waiting.
