Mixture - set appropriately

Mure useful is sometihng like:

Mixture - rich below 5000

That's the problem I was trying to point out. Is the average pilot
reading that going to interpret it as 5000 ft. MSL? Probably. It
also doesn't tell you what to do above 5000.

I often fly to an airport that sits at 4,600 ft. It is also common
for OATs to be 100 - 110F or in summer. Full rich would definitely be
a bad idea at that density altitude.

I think it's important for the pilot to understand the effect of
mixture at higher density altitudes and be able to set it
appropriately, rather than blindly following a checklist instruction.
There's no single instruction that will be applicable in all
situations.
