Building on that I find these reports to be lacking in that they assume just because someone got "rest" before a flight it means they actually slept. With as much day/night cycle flying as people go through when you sleep and when you rest may be two completely different times. I don't think the rest rules can really address that well.

For instance there are situations where (under the rules I fly under) I am required to take 16 hours of rest... That's just an awful idea. I'd rather take 9 in the hotel room and get home sooner then "make up" the rest period at home, 16 hours ruins my sleep cycle, where 9 hours would be perfect.

Now not saying that's what happened here, but it's something that I think is often misjudged.
