Ok, I think I understand that part, but what about this. I'm going to use an example here and say you need 300 exp to be promoted to Commander Grade 2, but 250 exp to be promoted to Colonel Grade 1. If the exp needed for a total differnet rank is lower then the exp needed for another grade of a lower rank, then is it possible to get to get that next grade of the lower rank, even if you have the exp to be promoted to the next different rank?
