Yeah, a real disaster.
What a disaster for Magnus

Carlsen has made a pathetic attempt to redeem himself a bit, having a performance rating of fifty points higher than everyone else, and winning the tournament by a full point, but has obviously failed.
But seriously, how good at chess must you be to lose rating points for placing clear first in such a strong tournament?

Elubas, he did not lose points, he went up 0.1 points! LOL
He lost rating 1.2 points from the Gashimov Memorial, but he won 1.3 points from a game in the Norwegian Teams Championship. So he is up 0.1.

Interesting to note: Anand's performance rating at the 2014 candidates was 2843 (or maybe it was 2834), lower than Magnus's performance rating in this tournament.
As of round 7, his performance rating is only thirty points higher than everyone else in the tournament!
