@ktverdov: This round of the food benchmark does not have a separate validation set, and hence the scores on the leaderboard are the final scores for this round. We release new test sets at the end of each round. In the subsequent rounds we will ensure to have separate public and private scores.
The recall score will be used as a tie breaker. So if two submissions have the exact same (upto 3 decimal points) precision then their order will be determined by the recall scores.
