I don't fly Boeings but I can tell you that a full flex take off with the 380-800 gives about 62% Thrust and at 'Thrust Reduction' it will actually increase to a value based on the 'Derate Climb' selected in the FMS (EA engines). So we could easily get a 15 to 20% thrust increase for the climb.

As long as all performance requirements are met then it works for me
