Hi TangoAlpha... quote.. I jokingly said pull the mixture and find out. She didn't think I was joking.
Must admit I have never tried that, maybe next time with an Instructor...
On the Ground, after the power checks, it's check idle RPM, to be 500-700 rpm. However in the air even pulling the throttle as far as it will go, I have only ever seen it drop to 1300 rpm minimum... Obviously the windmilling effect.
.
btw... Just remembered... Many years ago, when I was still wearing short pants, I had a model 10x6 free-spinning propeller on my push-bike. It spun quicker to tell me if I was riding into a head-wind or not ( as if I didn't know.! )
