How how many matches i need win to rank up In mcc

How how many matches i need win to rank up In mcc And i need to lower the rank pls help me!

4.3

I think it could be like 1 game for the championship series, but like 3-5 wins for Halo 3 and stuff.

I have no idea. I wish 343 would at least give us a hint as to how the ranking in MCC works BEFORE we all stop playing it.
