Yes, I used simbrief and the simbrief profile provided by Inibuild (passenger variant loaded with 247 pax). I have added 15 min extra fuel (3140 lb) and selected 5% contingency fuel (4131 lb). Block fuel 103,223 lb for a trip that require 82,624 lb.
I am at 3/4 of my 7h25 min flight, still with about 3500-4000 lb extra at each waypoint and still have the same indication in FMS.
