1. It's 'brake' not 'break' - 'break' is not a word you want to see associated with an aircraft.
2. The various take-off related speeds don't have a single fixed relationship. For example:
- either of Vmca or Vmcg may be smaller
- V2min must by definition be not more than V2 (you have V2min>V2)
- V1 and Vr may be equal
- Vrmin may be set by 1.05Vmca for some cases (hence Vr>Vmca)
