Here is how 2 days off would work day 1(first day off)- come home and sleep for 6 hours then be up from maybe 12-1pm until 10pm then sleep all night. Day 2 up at 8 am go to bed at 10 pm sleep all night Day 3(back to work)- up until noon sleep noon until work time.
Looking over my calendar he usually keeps them 80% on his First day off so that way his next FULL day and night and next morning is free.
