What happens is a company employs an expert to assess their FRMS and rostering practices, who comes in and say's "you got to be kidding, this is not clever" (obviously couched in much more politically correct terminology). The company than for the next dozen years or so states, well we got Dr Sleepexpert in who is a world authority on fatigue to look at our roster system and he see's no problems, in fact he thinks we are at the cutting edge of rostering best practice. Also we have this shiny FRMS that ticks all the right regulatory boxes, so vee haff a full scientic model to show you are not even remotely fatigued and are a lazy pilot, here, take a warning letter and go and cower in the corner.
