The deviation requirement applies only when there are enough plays to populate a full leaderboard. In tiers like Hackmons which see very few players, provisional alts still saw the leaderboard right before the reset. As soon as more people start laddering the provisional accounts will get pushed down and off to make way for those that are not provisional.
TL;DR it's not a problem you just gotta wait a little guys!
