Obviously the community would accept or acknowledge such a hack ... but mathematically would it work, or does the Elo system have something to prevent this?
My impression is that, very roughly speaking each time you play someone, your Elo goes up or down depending on whether you win. And how much it goes up or down depends on the disparity between your previous rating and your opponents.
- If you beat someone who was better than you it goes up a bunch.
- If you beat someone who was a little bit worse than you, it goes up a little.
- If you beat someone who was very much worse than you, it goes up a tiny amount.
But I assume that even if you play people who were ridiculously worse than you ... is still goes up a bit?
So could you hack your "rating" by playing tons of games against people who are much worse than you ... such that you'll never lose, and your rating will keep going up and up, even though you're not getting any better?
