Anyone have any experience maximizing the amount of hours that running unit operators can work (dual-unit site with other unit refueling) under the new fatigue rules? Most basically, I see that 10CFR26 would be limiting by the need for 2.5 days off per week averaged over a cycle, which would necessitate a 4 on, 3 off, 5 on, 2 off, 4 on, 3 off, repeat.
