Static. I'm too cheap to buy a telemetry system lol.
When possible, if I'm concerned about being near the limits, I will fly with my watt meter installed. Static test with my Sea Duck was 60 amps, but while flying I only hit 50.
If the plane was at a standstill and you hit max throttle (hovering or hitting full throttle on take off) I could imagine hitting the full amps, but that's rare and very short.
