Most pilots seem to think cycling the prop is just to
circulate fresh warm oil. Give the system a moment to have
the rpm stabilize to see what is happening.

Leave it there a moment? Hmmm, when I transitioned to the Bonanza, my
first constant speed prop aircraft, I was told by the very experienced CFI
not to let the RPMS drop too much during this pre-takeoff item or it would
place a high load on the engine (I believe his analogy was like shifting a
car into 4th gear while driving at 25 miles per hour).
Not true?

I cannot remember where I read it (sometime in the past year), not to
allow the rpm to drop more than 500 rpm during the prop check at runup
rpm.
