GAC Matchmaking

Anedoctal "evidence"...but i haven't been "cleared" in GAC for at least 9 matches in a row or so...and usually playing opponents +1M above me (i am under 4M)...i would lose many matches, but would usually have at least one surviving team.
Yesterday i was cleared...opponent actually had roughly the same power as i do...(i lost because i could not clear one enemy team...Qui Gon in rear)
There is more to winning and losing than roster...
