Worked 2days, 2nights, 4off, also worked the 4/5 option at BY in the late 90's. Preferred the 4/5. Weekends were either totally free or totally working. Also meant you could slot in a couple of O/T shifts without taking too much of a hit on your time off.
Another variation for 24hr cover was the RAF MATO pattern.
Day1 = Afternoon
Day2 = Morning + Night
Day3 = Rest
Day 4 = Afternoon
Day 5 = Morning + Night
Day 6 = Rest
Day 7 = Off
Day 8 = Off
The only good thing about this was you always had hangover recovery time before afternoons!
