Given that Vr may not be less than 105% of Vmc I'm not sure what the problem is. V2min is also restricted by a margin above Vmc.
The two speeds reflect two completely different and separate scenarios.
One defined by an ability to stay within 30ft of the centreline on the ground and the other defined by the ability to fly in a straight line after a deviation of no more than 20degrees in the air.
I can't continue to take off if I cannot control the aircraft on the ground (Vmcg) I can't attempt to fly until i'm above the speed required to fly the aircraft in a straight line (Vmc).

Reason: got my 20s and 40s mixed but JT doesn't miss a thing.
