If the majority of the people running the dungeons are doing it for tomes, they should be using premades. You skip the queue, you skip all the CS's, you skip all the mobs you can, everyone wins.
Versus not using a premade, where you have to wait in the queue, someone's probably watching cutscenes, and there's a fair chance that someone's going to accidentally pull something skippable.
So why the hell would you Duty Finder a speedrun?
