How about the new FAR117 that is used in the US and Saudi Arabia, where pilots could fly 6 sectors per day, max rest time is 10 hours regardless of what time of the day you get your rest. 30 minutes after chocks on is considered part of the rest time. And the best is that pilots must sign a paper before each flight that they are fit to fly??? and if for any reason the pilot could not continue the full 4 or more sectors, then he is at fault because he already declared that he is fit. And the best part if you call fatigue for any reason, then you have to answer to the computer who would tell you that what you feel is not right because according to its calculation you are legal to fly.
