Start weight 50T End weight 30T (only the lineage version can carry this amount of fuel)

All Engines operating
FL 300 - 869 minutes
FL 250 - 872 Minutes
FL 150 - 850 minutes

One Engine shutdown
FL 150 - 868 Minutes
These numbers corroborate my initial statement that max endurance is independent of altitude.
