I saw that the rankings changed dramatically since the competition ended (not before to after deadline, but changes have happened after the deadline), and people who were super close to the top now have really bad scores (>0.9 down to ~0.17 for me). This looks really odd to me, especially since submitting the same code in practice again gives me closer to 0.9.
What’s going on? Has something gone wrong with the grading of the challenge? A lot of scores seems to be pretty much spot on 80% off, which would make a lot of sense if some submissions were never rejudged with all test cases (20% are graded before deadline, the rest after).
Edit: just tried running the current “winner” in practice and my submission was better than it.
