The gist is correct, if you win you go up, if you lose you go down.
Things that vary the amount up/down are team balance and personal performance.
By team balance I mean it does try to give balanced teams, however it's never going to be perfect, so if you win against a weak team you go up less than if you win against a strong team. i.e. It's proportional to the relative team strengths, or another way of saying it would be it takes into account your likelihood to win. And obviously vice versa for losing.
For the personal performance effect this is to do with how much XP you earn, and therefore correspondingly your position on the scoreboard. If you position near the top of the scoreboard you go up more for winning, or down less for losing, than if you position at the bottom of the scoreboard. But a win will still always move you up and a loss will still always move you down.
I'm pretty sure if you have leavers and still go on to lose/surrender then it still counts as a lose, the problem with doing something like "well just give the winners the win, and the losers with the leaver stay the same" is that it's opening the system up for abuse/farming, so I'd think that they'd never do that. What does happen is leavers accrue ever increasing penalties so they can't keep ruining it for everyone else, and if they're causing real problems then they get banned. Personally I think the penalties should probably last a bit longer than they currently do, but I've also heard from several people that they are getting penalties for doing nothing wrong. So I'd hope once some of the bugs are ironed out they'll think about increasing penalties.
