We are not reinventing the wheel here. For modern jet era aircraft, the procedure has never changed. Minimum fuel, 60-70 as prescribed % N1 opposite engine to required thrust. I have as well heard of a 747 swinging the nose if 1 or 4 coughed, I suppose the same issue exists with the A340. None the less, A 2nd person for safety should always be standing on the brakes as well, brakes can usually be set but pedals must be occupied by both people. Pre FADEC motors, this was usually done to adjust the fuel control or verify proper power could be achieved.
