That said, I haven't actually tested the system yet. I'll try and find time to run a test ladder this coming week to see precisely how the ELO rating system works.
That's not 100% what I said though. You should only be able to gain skill rating beating lower ranks through your win streaks and also you lose skill rating when losing against people of equal skill rating and lower skill rating. There is abit more to it then that, but that's just the basic idea.

Since we're not gonna have thousands of players it can be something different anyway. Maybe what king is suggesting.
