If you turn in every one run, it means you’ll get out of barracks every ~16 min, GC wise it’s the most efficient, but it has its drawback, you won’t be very discreet.
I find it better to get out every 3 runs, so one time per hour, avoiding to run into the same persons too often. Teleporting outside instead of getting out might also be a good option, as the path to come back is more natural than the one when you get out and have to re-align yourself to target the right NPC.
