Best I leave 742 comment to Mutt if that be appropriate.
If the takeoff is seriously Vmcg-limited, then one is likely to be (near) aft CG. In this case, especially in the wet case, NWS is not likely to be of much use at all .. it is for this reason that the certification process doesn't consider the potential benefit of NWS.
Did anyone miss the reference to 1.3kt/kt ?
An uncorrected min V1, aft CG, max thrust takeoff with a critical (upwind) failure in a significant crosswind leaves the crew between a very big rock and an equally big hard place .... and looking very, very seriously at the grass ....
