.. also, consider that Vmcg is for fairly critical conditions .. aft CG, no NWS, rated thrust, min weight (generally at very low fuel with min yawing inertia).
In the normal operational environment, we don't go anywhere near the actual Vmcg for the day. Given that the onset of controllability problems generally is quite rapid (in terms of speed deltas), we don't normally need to worry too much.
However, several of us restate the hobby horse, regularly, that one needs to be cautious if the actual conditions tend toward the certification configuration, especially if there is an option to use a higher speed schedule to avoid the problem region. This crops up in the ferry/positioning scenario from a non-critical runway ... if the crosswind is significant, consider using a higher speed schedule (but still within the RTOW data for the runway).
