Congratulations to all winners. \nI made a costly mistake by not considering month old submissions as a final one. It could have fetched me a silver probably (3.611). The lesson is to have a strong local CV measurement/tracking mechanism and not get carried away by the latest submissions. I went on overfitting to public LB while lost on private LB.\nHope I will do better next time. \nCongratulations again!
