212man - I don't know about your AP but mine in ATT mode (normal selection) copes very well with flapback, inflow roll and tuckunder in the transition from the hover.
My point is that you could have a lower Vmini if the pitot system was good enough but none seem to be. It is easily possible to control the aircraft on instruments below Vmini but it won't be certified that way because of the inaccuracies of the pitot system.
