That sounds like a good category; I would probably run it as well. Maybe call it "All Bungee Spots" or something similar.
In All Chests, you can essentially go for two chests at once with two players, and that's why 2P is an option in All Chests. For other categories, a 2P run would ostensibly follow the same route (the exception being 100%).
Why do all runs have milliseconds on the time? There doesn't appear to be any important reason for them (as the game isn't optimized enough) and it would just cause extra time spent timing runs.
At some point categories should be condensed under Miscellaneous, such as All Chests, Diving 100%, and theorized Bungee and Photo Spot 100% runs. Other than that, level leaderboards could be utilized at some point for different activities like Off Road Racing and Motor Fest.
Since you can get digital copies of the game on Switch and digital (presumably) lowers loading times.
Three lategame categories that would make sense for the leaderboard are All Silvers, All Golds, and 100%. Obviously, these won't get a lot of runs, but they are categories to look into.
All Silvers: Pretty straightforward. It would require getting all silver keys on Wii version and all silver stars on Switch.
All Golds: Not as straightforward. All gold keys on Wii, but I'm unsure what this would be on Switch. Gold keys/stars don't appear to be present here, so this is uncertain.
100%: Pretty straightforward. All gold keys, photo spots, and treasure chests on Wii. You'd get all silver stars, photo spots, treasure chests, and animal photos on Switch, and maybe max level, but I'm not sure. (You would also have to get '5's instead of '4's where applicable and get all fish in Scuba Diving.)
As I said before, these are categories that don't need to be added any time soon, but perhaps keep them in the back of your mind just in case.
This would be a pain to verify. You'd have to watch every frame of the run closely.
Who would run it though? Timpani doesn't seem to want to do a shortened AUM.
I don't think you should warp to Salt-Pile Isle in Luncheon. There should be a greater penalty for not doing the jump.
Bowser's has no need for a warp, as the ogre island is right below the painting. Metro should certainly allow warping back to the Odyssey. In my opinion, Luncheon should allow a warp to the Odyssey, as that would be slower than if you did the jump.
