My view is inappropriate use of the word fatigue that's all. I've suffered from fatigue for sure and I might be wrong as the report didn't include the Captains roster leading up to the event.
All too often the F word is used when sleepiness might be more appropriate e.g. the need to sleep.
What you say is very interesting, exactly what roster pattern were you on when you experienced fatigue and for the benefit of all of us how were you able to differentiate between fatigue and sleepiness.
