I was just wondering: how does the leader-board work? From what I've noticed, the leader-board is based on:
1) The number of problems a user has solved (the more problems you've solved, the higher you are on the leader-board).
2) In the case of two users solving the same number of problems, the user who solved those problems earlier is higher on the leader-board (the faster, the better!)
Are my observations correct? If they are, I've noticed some inconsistencies on the leader-board.
This week I wanted to solve the problems as quickly as possible and I did. I solved all of the Level 4 Number theory & Algebra problems and was on top of the leader-board for a whole day (I felt so happy!!).
But the next day, for no reason at all, I kept getting bumped down! From 1 to 3, from 3 to 4, from 4 to 6. It seemed like I was getting bumped down by more recent problem solvers.
But the most confusing thing happened today. I got bumped up to 5 on the leader-board even though I did nothing! (well, what could I possibly do? I had already solved all the problems and didn't get selected to submit a solution)
I do remember one thing. I solved two unsolved Level 4 Geometry & Combinatorics problems today. Did that have something to do with me going up the leader-board in Number Theory? Are the leader-boards of the olympiad math categories connected somehow?
Another question: is solution submission a criterion for the leader-board? Are users who've submitted solutions to this week's problems higher on the leader-board?
I'd be really happy if you explain how the leader-board works and I think it would benefit a lot of users if the leader-board were more comprehensible.
Thanks in advance!
