pgt: When I set up a Hyper game and say minimum BKR 2200, how come a player with a BKR of 2056 is, consistently, able to accept the game.

Either the site isn't working or it's operator error. The "Are you sure it's plugged in?" question here is "Are you definitely setting it up with 2200 on the left and 4000 on the right?" ;-)

I don't really enjoy playing a game where I stand to win 2 points and lose 12, but such is the ridiculous rating system that that's what happens.

I hear ya, bro. I feel your pain. (Well, I do when I lose ;o)

While I'm on the band-wagon, why do the same points apply when you win or lose an 11-point match 11-10 or 11-0???

The score is for the match, not the games in it. That's just part of what "match" means. The real question is: why do the same points apply when you win or lose an 11-point match or 1-point match???
