Duhre, win-loss is a meaningless metric due to the fact that PS uses matchmaking. Unless you've got a team that's very good or very bad, your win-loss ratio probably doesn't change much from tier to tier, even though your rating probably changes drastically. That's because the better you are, the better the opponents you'll be matched against. So the only thing is *makes sense* to look at is whether rating correlates with usage, and you get that from "avg. weight."
