The average actual fuel consumption for the 25 cycles in Fig. 3 is 13.1 L/Cycle, while the average manufacturer's lower and upper bound estimates are 12.8 L/Cycle and 17.9 L/Cycle, respectively. Though the actual fuel consumption lay in the range [12.8, 17.9], the difference between the lower and upper bounds is about 40%.
