Yeah you queue up for 10 floors at a time with either a matched or premade party. For a matched party you can only go up to floor 30; you can also start from either floor 1 or 21 (once you've cleared 1-20 once). Since it's a pretty efficient leveling method most people will just spam 21-30, which is quite easy.

The floors after 30 get quite a bit harder. You have an hour time limit for each 10 floor set, so if you're running 21-100 it'll take at most 8 hours (for the lower sets you're probably actually taking more like 30 minutes, and from what I've seen time is less of an issue than in past deep dungeons here so even in the higher sets it'll probably be more like 40-50). We were just blazing through in my run last night though and completing even a lot of the high sets in like 30 minutes.
