The best one or the last one in the 10 submissions as the final result?

We have 10 chances to submit. And which one will be used for the final ranking?
The best of them and the last of them?
And can we know the benchmark result after each submission?

We will use the best submission of the 10. Results will not be made available after each submission. The OC20 validation set can be used to help give an idea of your model’s improvements before making a submission.
