You ARE quoting the fuel load, not the thrust and you are wrong. You are talking about the airplane that I fly. I just quoted you the correct number from my manual. And I was NOT the original person who stated that the 900 was 30% more efficient than the 175. I was just asking you how you thought it made sense for it to be even 15% more efficient while weighing less than the 175 and having 10,0000lbs more thrust (as you claim) which would be a drastic increase in fuel flow and therefore NOT effiicient at all. Check your facts...ALL of them.
