So, how is that different than any schedule? If you're working on a 24-hour schedule, obviously interruptions can screw things up. It sounds like he's getting plenty of sleep, so it would probably be okay to sleep an hour less every so often. He probably also has plenty of time on the weekend to reset to his desired schedule if interruptions during the week caused his schedule to shift. I'm wondering what sort of magical schedule would fix the supposed problems you've proposed.
