My knowledge of these things is limited to the bits I picked off this thread. My understanding is that throughout the speed range the feedback is the response of the airplane in terms of pitch rate and Nz. At low speed the pitch rate is dominant, and at high speeds the Nz is dominant, but both components are present all the time. The response of the airplane in terms of q and Nz is not affected by errors in the measured airspeed.
