What Mil means is:
3 days of 0800-1200, lunch, 1300-1700 = 24
3 night of 1630-0100ish, sleep til 0630, handover at 0730 = 28.30
3 days off
52.30 divided by 9 days = 5.81hr per day = 40.6hrs per 7 days.
Bearing in mind that during the '6 shift', sleeping after flying allowed for 3 days off, combined with the 3 days off granted at the end, he worked a 1 day week of just under 6hrs.
