If properly done, you can clear MH in 3 hours and BT in like 6 hours, so in theory in 2-3 days you can clear all t6 content.
The setup is also fairly good, since u use same setup for whole hyjal, and in BT, we usually do Naj - Sup - Akama - Teron - RoS on first day, rest on second, and atm Illidan on 3rd day but we probably will fit it in the 2nd day once we menage to get that and Council properly done.
Ofc after you "farm it", learning nights don't count.
