I guess that as I haven’t worked on an aircraft that is capable of 60 – 80% Derate, I’ve failed to see your point in real life.
For clarification, V1min tracks VMCG and not the other way around. From the above you can see that the V1 for the accelerate-go is below V1MCG, it is therefore getting forced up to meet the V1MCG.
