Do you operate lean of peak, out of interest?

I've got an EDM700 and I certainly do, including leaning on the
ground. The engine is an IO-540-C4.

I flew the Argus equipped with Wright turbo compound engines and
we operated them leaned to 10% drop from 'best power' (peak) for
years and years. That was the recommended procedure from the
manufacturer.

Be aware however, that answers
quite often give me trouble.
