I've played mostly 5 min games till recently when I've started playing only 10 min games. I have been 1171 points for the last 18 games. How is that possible?
The only reasonable explanation is that you are playing unrated without realizing it. Could it be a site error? Sure. But the chances are slim.
Yes that's it. Only checked one of your games, but it was indeed unrated.
