Leaderboard equivalent R2, RMSE

I See that multiple teams have submitted on the latest dataset and on the leaderboard have equivalent RMSE of 13.0085 and Rsquared of -2.2701.
Is this a reporting error? Or should we believe all teams have the exact same results?

If you miss a week, then that week will be automatically populated in the following order:

  • Using the most recent prediction for that week, if you predicted for future dates
  • Otherwise copying the previous week’s prediction for that grid cell
  • If there is no previous prediction for that grid cell, using a no-snow estimate ( 0.0 )

Your case is the last one, that is why many teams have the same score until a new column will be evaluated
