I pretty much go by IAS. Given a MP, RPM, and Mixture combination, I know
what percent power I'm running. From experience, I know what IAS I should get with
that... anything else and something is different (like more aft loading, for
instance). Higher altitudes might mean better TAS, but you're usually affected more
by the higher winds aloft than by the IAS/TAS increase. As I said.... usually
something I fiddle with when BA (bored aloft)...
