I'm going to perhaps excessive lengths for the sake of anonymity. For the sake of the discussion our "state mandated min" would equal your CMR. Diversion plus reserve. No alternate flights were in place before the new policy and still are.
There may be an issue with rounding. IE: Cont. for instance might be 601k or 699k. It could be that, in either case the figure is rounded down. I'm trying to find out more on this. Perhaps our old policy used a blunter instrument for calculations and all rounding was done up.
Do you find yourself occassionally ordering more fuel or is planned fuel always satisfactory?
