In yesterday's Educational round, my submission for problem E which had WA on testcase 3(which was one of the samples ) was penalized. I suppose this was due to the testcase not being marked as a sample in the judge. (Not completely sure though, I have used Polygon only once)
Here are my submissions to the problem: 
Here I should have been penalized for only the TLE on testcase 17, but was rather penalized for two submissions.
MikeMirzayanov, adedalic, BledDest can you please look into this and fix the problem.
Thank you.
The rule has always been penalty for non test 1 afaik
Oh. I remotely remember not being penalized in some other Div 2 round for WA in a sample which wasn't testcase 1. This might be fuzzy memory though.
You probably was penalized for the accepted solution
I think it's a good idea to have penalty only for non-sample testcases.
-> hell
