No exactly that John. I had in mind a definition (interpretation) of Vmca which includes either stall limited or lat / dir control limited, i.e. stall is classed as a limit of controllability (stall in the asymmetric configuration, i.e. not a straight stall).
Thus, where stall occurs before the lat / dir controls are limiting, defines the pitch control limit, opposed to the more normal lat / dir control limit being reached before the stall speed.
