Seems like the challenge has been extended, but wasn't able to find our the new deadline.
Created by Fan Zhu fanzhu Hi @fanzhu,
Thanks for your post. We are currently waiting for Round 2 validation data and therefore do not have a deadline for this round. We'll update all participants as soon as we find out more.
Until then, Round 1b will remain open and will allow one submission per day, using the boot Ladder Boot scoring approach described on the wiki.
Cheers,
Robert
