Educational Round 73 rating change policy

Revision en3, by JaroPaska, 2019-09-20 12:47:08

Hello everyone,

I participated in the Educational Round 73 contest and solved problems A to E, but I had a bug in my solution to B and the round was unrated for me in the end. However, despite this I would still be looking at an increase in rating of about +25 (which is admittedly still quite disappointing compared to the +214 the CF-Predictor was claiming during the contest).

I don't think that it's particularly fair that the people that would have had positive deltas even with a 0 for problem B got denied their rating change. By my standards I had an outstanding contest yesterday, and while it sucks to get screwed over by the checker for B, it sucks even more to solve 4 other problems and be denied that only because I had a wrong submission on B (if I just skipped over B and didn't submit B at all I wouldn't have this problem). I'm sure this happened to some other people as well, and that sucks, because they were also probably having a really good contest and in the end got nothing for it.

To clarify, the purpose of this post is not to bash on the fact that there was a bug in the checker for problem B, I understand that things like that happen. I just don't like the way the rating changes were addressed afterwards. To finish on a lighter note, you can try and find the bug that cost me ~200 rating.
