Ghetsis may be the primary story objective, but there is an E4 rematch in there, so keep going son.
Myself, I've tried this with Ruby and Emerald a couple of times, my best being 7:22:38 on the latter (my Ruby's internal clock is dead, but all that really means is that I can't get the shell bell anymore). However, I was unaware of the rule about save penalties, so just keep in mind that that's my time before those. I know there's at least 15 minutes on top of that because of how much of an issue I had with Wattson and Norman, and I learned as a kid to always save before taking that final step into the league challenge, but I don't have a precise count.
(as a side note, Emerald's Trainer Hill is basically a speedrun minigame...I'm surprised they haven't revived that concept like they have with the Frontier)
Protip: If you want to solo with Mudkip, you'd better know how to dodge the Aroma Ladies.
Edit: Holy shit, KoWL, you actually completed a single-segment run of Black? O_O
