0.05% means that one occurrence every 1000 flights (assuming 2 pilots) or 500 flights when a relief crew is on board...it sounds quite alarming
Do remember that the crew limit is set vanishingly low and, even if these figures are correct, they do not indicate skippers rolling aboard roaring "Single up to the bow spring; slow ahead!"
My point was that putting figures, specifically statics, without mentioning how they were extrapolated can produce distorted results. If those figures are correct we can deduce that at any given time there is at least one pilot over the legal limit at the controls. Since I take about 250 flights per year, I can also say that once a year, statistically, the pilot at the controls of my flight is above the legal limit.
