Yup, im sure about that. Got a V1 of 104 from our boeing performance tool lately for a takeoff on contaminated runway (slush, 3mm), crosschecked it with a Vmcg chart and our Vmcg was around 98kts or so, -700, derate 2 (18,5k) at sealevel pressure and something like 0°C.
Vmcg varies a lot depending on model and selected thrust setting, quite a nice thing during winter ops to be able to reduce V1 by a lot if necessary.
