In Halo 3 players are promoted until they cannot hold a consistently positive K/D ratio. This is why when you play by yourself you should assume everyone on your team will play poorly and the only way you can win is to go massively positive to carry them because they are stuck at the rank trueskill expects them to be at because they cannot win consistently. This is why everyone on your team sucks.
The Peter Principle
Going postive has nothing to do with ranking up. I've boosted kids to a 50 in doubles in 17 games and they went at least -6 every single game
