why doesn’t my rating change?

Are they doing this? :crazy_face:

I don’t think so. They would be deliberating about if it should be rated due to issues related to PREFPERM.

PREFPERM wasn’t even present in Div 1. So I don’t see a reason why it should be unrated for Div 1. @admin Can you please update Div1 ratings at least? Once a decision is reached you can update/not update rating of other divisions based on it.



Thank you for clarifying this. I was constantly checking my ratings all day.

So many constructive problems. Can we call it a perfectly imbalanced round?

The ratings have been updated for all. For users who were affected by the issue in PREFPERM, and who would have had their ratings decrease, we have made the contest unrated for them (ie. +0 rating change). There were 286 such users across all divisions.
