Which submission is picked for the leaderboard

When we make multiple submissions, which submission is used for the leaderboard ?

Your best submission so far.

I do not see my best submission being picked up as final one. Or maybe its a bug. Or maybe I am missing something.

My best submission can be overfitted to the LB. Can I choose the submission for private LB?

@sagol I think there’s some confusion.

Your place on the public leaderboard is determined by your best public score.

Your place on the private leaderboard is determined by your best private score. You just can’t see the private leaderboard until the end of the competition.

So, don’t worry, your performance is always assessed by your best submission to date.
