wilco/cls A340-600 fuel flow question

Morning fellow virtual aviators,To those who have the wilco or wilco/cls a340-600, what would be the ideal fuel flow scalar?I have the latest wilco service pack and the fuel flow scalar on that is 0.73?I'm asking this because the fuel burn values seems really low for an a340-600. E.g I did a 2800nm flight, roughly 6hrs (average winds= -16kts) @ mach 0.84 with 386 pax & 80,000lbs cargo. Total flight fuel was 105,000lbs. This is about the same i've seen on a 777-200er rw flight report doing the exact same journey.So i was wondering if it was just me or the fuel scalar (or whatever it is in the .air file that control fuel burn) is a little inaccurate?CheersWalter
