Hi @hunim - Thanks for the post. The eligibility rules for this challenge are set and won’t change. Keep in mind that these criteria apply to the team representative, so if you’re interested in participating in the Prescreened Arena you may find an eligible participant to team up with.
As you’re probably also aware, the score on the Open Arena is not necessarily representative of how solutions will perform on unseen data. This is why final rankings will be determined by running solutions on an out-of-sample dataset.
