I think there's something wrong with the math
Efficiency numbers quoted are per pax for full planes (I guess considering the max legal amount of seats)
Also, the Qatar 787-8 has 254 seats, 232 in Economy

Analysis does assume flight are operating at 100% capacity, which is likely to be improbable.
Airlines can mix seating depending on 787-8. I got the figure 232 here: https://en.wikipedia.org/wiki/Fuel_economy_in_aircraft
