Worth a search of the archives as Mutt and I periodically do this one to death. Useful to recall that the effect of crosswind on real Vmcg varies from 0.5 kt/kt through to something in excess of 1.0 kt/kt .. and, if your crosswind limit is a lot of knots, and you are light and at aft CG and on a min speed schedule ... life could get very interesting if one goes quiet.
