Is it necessary to have an A+ in both reputation and loyalty in order to move up from D2 to lower-level D1? Or is there some leniency? (And I know that my current resume isn't impressive, I'm just planning for the future)

I had A+ rep and A- loyalty and it told me I needed better loyalty. Not sure if that means A would have been good enough.

i thought a- loyalty was good enough for some lower d1 teams, i am almost positive i took over tulsa in CUSA in rupp with an a- loyalty. well, now that i say it, actually, it was an a- reputation, i think. ok, so i think you actually need an a- rep, and an a loyalty, to move up to d1. some programs require more. like, with overkill success for harvard, i couldn't move from a big 6 program to harvard with an A rep - i guess they require a+. maybe all of the ivy league does? i wouldn't be surprised if there were schools that needed a+ loyalty too, but, i can't remember specifically seeing any.
