I was thinking the category(ies) could just be (x)char with the following 3 addenda: In each segment of your run, you must 1) clear the Boss Room on each of the 10 normal floors [for Labyrinth levels, this means clearing both Boss Rooms], 2) clear the entire Boss Rush, and 3) clear Blue Womb (???) by defeating Hush. Alternatively, we could do all of the above twice for each char; one segment going up to The Chest and one segment going down to Dark Room. If you're interested in either of these, let me know which you prefer and what #char run you'd want to do. I personally am interested in running 1char 100%, but I'd try others as well. I figure if people are interested Hyphen-ated might open up some new categories under the "Misc" tab. Also if you've got any other thoughts on rules for a 100% cat, let me know! I'm totally open to feedback, this is just a rough idea.

Also for what it's worth, I prefer the single-segment 100% to the single-session double-segment 100%. It would just be too much grinding for any category besides 1char 100%. That being said, if anyone has their heart set on it, I'd be down to run single-session 2-seg 1char 100%. But if people want to do 100% 11char or 13char runs or anything, I think we should go with just the single segment per character so it doesn't become a 22 or 26 segment run, that's just nightmarish.
