It's for this direct reason that every pilot and instructor who ever
flew our airplanes was subjected to as an integral part of our checkout
procedure, an in-flight demonstration on how we wanted our engines
managed throttle wise UNDER NORMAL NON EMERGENCY CONDITIONS.
Smooth throttle and prop use use and in relevant cases correct use of
cowl flaps is the key to long engine life. It's the smooth management of
temps and pressures up and down that's important, and this means
strict focus on how power is transitioned from idle to full and visa versa.
Aside for an emergency condition, any application of power up or down
that isn't smooth indicates poor planning on the part of the pilot.

Amen, brother!

Thanks for restating it in better terms, Dudley.
