Hello, this is by no means an accusation. I'm just curious if teams with 0.21+ scores on the leaderboard are using test data in training, validation, post-processing, test time augmentation, etc. Based on my local evaluation, using future information can get at least a 0.006 boost in the score. However, all these usages of test data are not allowed for the final submission according to the rule.
