@greyslovr depends on our call time in the morning. Work day is generally 13 hours long, (12 hrs shooting, 1 hr lunch) but can be longer

— Karin Gleason (@karingleason) July 23, 2015

@greyslovr correct. "Turn around" time from wrap to next day call is 11 hours. So if we wrap at 8pm tonite, we can take 7am call tomorrow
