It seems that you are better than your rating because you did not lose a single game against opponents that are supposed to be better than you. I suspect that you can also get a significant number of draws if you play against IM's and GM's. It is also possible that you can get better result against humans if you decide not to agree to a draw in equal positions unless it is a simple draw even if you do not have a plan to win and to continue to play when you hope for a mistake of the opponent.
