Yeah, I hear ya. I just don't think an occasional simulated engine-out
practice is "needlessly".

And I still want to know *how* it harms the engine. Exactly what parts will
be damaged, and why?

Can we agree that idle power/full power engine management will cause
more wear and tear (AKA: "Damage") to an engine than steady-state
operation?
