You don't get a level per run now, so you will get at most a level after the patch, probably less. The only time you get a level atm is if you have the roulette. A lot of dungeons can be run in under 30mins though, especially if you have semi competent DPS. Challenge log as you said is around 10%, and you only have a few(2 dungeons, 2 guildhests, 2fates and hmm, not sure what else) so that's not even a level and it resets next tuesday so that won't do shit really. 8hours is grossly exagerating. It's not terribly long, but it's still longer than that I'm fairly sure. Probably closer to 18-20hours.
