I use Kick's questing, running with HBRelog. Maximum 12hrs a day. Normally I'll be leveling 2 or 3 toons at a time in 3 or 4 hr cycles. anywhere between 20% and 80% supervised depending on workload at the time. You will, and do get stuck, but you get to know which zones this happens in most. Full looms to 80 (I dont have all looms, but I still use them even if they are wrong - latest paladin for example wore rogue leather looms to 80), and lvl25 guild boostage.
80-82 all of hyjal - dont move early, then all of Deepholm ( gonna need that for later dailies anyway). Uldum till 84, TH 84-85 ( although i often play 84-85 as dungeon and questing).
Time to level is based on /played for the toons at the end.
