It is one thing to have a limit of 1000 hours a year and a pilot clocks all hours flown even during rest on ULR flights. It is a whole different ball game if the limit is 1000 hours and a pilot only logs 50% of the flight time because he is resting 50% of the time, again in the ULR case.
There are some un-named operators who count 50% of flight time and still want the newer 1000 limit! This will push the crew into uncharted territories.
