The planes I've flown are less efficient at WOT, but get there faster.

WOT is gentler on the engine, but if it's only a sim, fuel burn and
engine
wear don't matter.

OOPS! WOT is harder on the engine.


OWT.




Actually, on many engines WOT is better than slightly reduced throttle
settings. WOT on the carbs provide a bit of enrichment for cooling.

Hmmm, when at cruise, especially above 5K feet, I always bring the
throttle back to where the MP just moves down a bit. I am not wasting
fuel that is not needed and I have heard that the butterfly valve
slightly tilted helps in mixing. Don't know about the latter, but
certainly I have found better fuel burn numbers. In cruise, not sure you
have to worry about using fuel for cooling.
