What makes power/pitch airspeed reduction on short final useful is that we can utilize the slower than Vso stall airspeed, in low ground effect, prior to the desired touchdown point rather than after.
Motoadve uses the AOA indicator/audio. Even without that, however, the airspeed indicator is not what I am willing to rely on at those slow airspeeds. The POH does not give the in low ground effect airspeed that his, or any 182, is at when it touches down. Wait, that should be when any 182 touches down properly.
