Dont know others can reproduce a similar result in the 40-day left of the competition, i.e 1.0 in just one submission.\r\n\r\nBtw, what would happen if we have more than three perfect scores at the end? Did it happen before?",

Namely, for two teams which achieved exactly the same score on the private LB, the earlier that submission was made, the better the team would be ranked.\r\n\r\nBest regards,\r\n\r\nShize",

Since both the leaders right now have had lower scores, presumably their method isn't foolproof.  I'd be willing to bet that there are a couple of sets that are dastardly hard to get right that end up tripping up some of the 1.0000s on the final leader-board.  So there's still an incentive to continue through June if you think you can hit perfect.",
