I agree I didn't say it right. But the procedure has some value. You
lean to peak at 10000', you are leaning to a safe EGT. THAT EGT will be
well rich (or lean) of peak at "dangerous" power settings (like 75% or
more) and you have found this rich (or lean) of peak by never leaning
all the way to peak.

That is what I meant. Sorry about the poor (actually incorrect) wording.
