Are there leveling rules for each MSQ section i.e. finishing ARR and being closer to lvl 60 than to lvl 50?

If I stream myself learning a route for a game should I use the "12 hour challenge" tag, or the "Speedrun" tag? I don't want to put the wrong label on my stream, or cause problems for myself or anyone else.

I'm new to actually running a game rather than watching someone else do a run. I'm planning on doing a stream while I learn the route for OoT. I kind of know where to start, but any help or tips would be greatly appreciated.
