You cannot know the sequence, only parts of it. Vef, for instance (not V1) must be greater than equal to Vmcg. V1 may not be greater than Vr. Vr must be greater than or equal to 1.05 Vmca, but who is to say which is larger, Vmcg or Vmca? Who says Vs is greater than V1? No regulation. It is a basic mistake to try and run a sequence that runs Vmcg, Vef, V1, Vmca, Vr, etc... the logic doesn't follow through.
