I submitted an updated version yesterday (12/10/20), will this be too late to get points from week 2 leaderboards or not?
If it is an updated version, it means you had already submitted a prior version; the eldest version will count towards week 2, as you missed the cut-off. The new version will count towards week 3.
and if I make a new submission would that accredit to the previous week? Given that the new model is drastically different to the previous and is only considered an “updated” version to avoid creating more than 2 submissions?
