For which game?
I know that super mario 64 and sunshine organise their individual level leaderboards outside of speedrun.com (on spreadsheets or similar) - I don't know if they allow runs done on 3D all-stars however.
For super mario galaxy the moderators have decided to not make individual level leaderboards for 3D all-stars because not many people would run them - I have made an spreadsheet for these runs that a few people have used however if you are interested.

MrMonkey & speedey_b, thanks so much for putting together the spreadsheet and sharing. I agree that single star would be fun for all 3 games but I’m personally most interested in Galaxy for IL’s. I’m a bit heartbroken that the mods made the decision not to add that. I can see that there’s only a few folks on the spreadsheet so far but 3D all stars is pretty popular I can see IL’s gaining participation if given a chance. I certainly would love to. But in the meantime the spreadsheet is great
Thanks! I agree it's a shame that it's not an offici leaderboard, but it's better than no leaderboard!
