Fatigue EASA, sick, interest, quality negligable cost difference on basic shift
Multiply the cost of shift by the cost of inefficiency equals the true cost.
12 hr compared to 8 hr

8hr= 1.37 by a conservative loss factor of 1.2 for handovers, supervision, sick, extra training
= 1.64 effectively hmmm
But they are dumb,
