Trust me, when they say payload is XX tons and endurance is YY hours They do not mean that endurance with a max payload of XX tons is YY hours. You can bet your last paycheck on it. And the figure quoted for endurance is specifically "loiter" time, whihc means only using enough power to counteract whatever wind is present. That certainly is not endurance in cruise at 80 knots.
