I'm too confused to rage about it but I guess it would make more sense to try to find out why. Either the machine is trying to keep me down or dodging a game just destroys me.

Just deposit intelligence at will.

Lolmatches updates at champion selection (they say so in their faq, which I've read after getting strange things like that) and therefore your last played game is not actually included in your elo or the curve.

yup, whatever your lolmatches elo is, your actual elo is dependent on the outcome of your last game... it could be higher if you won or lower if you lost
