Global Round 26 Rating Rolled Back?
By srijan050, history, 5 months ago, In English

Hello, Recently Codeforces Global Round 26 occured, and I was wondering why is it showing as "0" rating change in my profile, even though it wasn't the case two days back. I didn't cheat/copy whatsoever, and neither are my submissions skipped. So I'm failing to understand what exactly is the issue here. Kindly let me know if anyone has any idea.

Thank You.

You didn't perform better nor worse compared to your rating back then, so you didn't get any rating change.

      https://ibb.co/5hrMB6Z if you click on the user with the highlighted name, then you will notice how they are even lower rated than you, but they only went up by 4. It will make sense, trust.

    I had some +ve change two days back, if I recall correctly. And I don't think there has been a rating revision for this contest.

the algorithm for calculating rating changes returned a score of 0.5>x<0.5 so it became 0
