Interesting behaviour of Rating Changes

On the today's round I noticed something peculiar about Rating Changes. Particularly, let's compare my rating change and the change of a user taking 166th place.

  • My final position in the ranking is 151 and their is 166.
  • My rating before the round was 2378 and their was 2370.
  • My delta was +8, and their was +35.
  • My rating after the round is 2382 and their is 2405.

The interesting thing is the apparent lack of monotonicity. Finishing at higher position and starting with higher rating may not necessairly mean higher final rating.

Any thoughts?
