Since there seem to have been some misunderstandings, and I definitely haven't heard a definitive "no" yet:
-
Stages of 10 levels (e.g. 31-40) belong on the Level Leaderboard imo, since they are very clearly presented as individual stages (or in speedrunning terms, ILs) by the Level select menu. This would uncram the "Miscellaneous" tab, which would be reduced from 66 to just 6 categories.
-
Single levels (e.g. 37) should not be on the leaderboard at all imo, as they are too numerous, short, and replicable to really have any relevance. Just remove them altogether, nobody has even submitted a run of them yet.
-
Segments of 100 levels (e.g. 1-100) are where they belong - on the Miscellaneous leaderboard. They definitely have the nature of a full-game category.
