Often the problem is that peaks are so short in time that a lot of equipment won't see it.
I have equipment that records genuine peak currents. On the ground, I have recorded a pair of JR8511s waggling the tailplanes of an AD F-100 peaking at 10 amps for the two, so 5 amps each, these peaks were for just a few thousandths of a second and would have been the point at which the motor was trying to reverse direction, so it is stalled current plus the back-emf. In flight, on a small Grumania Eurofighter with 2 analogue elevon servos, it always records a peak around 4.5amps during each flight, but I can get close to that on the ground as well so the peak aerodynamic load can't be much, once again it must be reversing current occurring for a tiny amount of time.
