What Deakin suggests is that you get yourself a multi cylinder EGT
guage that can tell you what the temperatures are for the EGT and CHT
for ALL the cylinders.

Without that instrument and even with a single point EGT guage, you
have no idea where the CHT's are when you lean by that method. He
frequently characterized the typical Lycoming/Continental engine as a
group of cylinders flying along loosely in formation because the
temperature readings from one cylinder to the other can vary so much
you'd think they were from some other engine.

Maybe you've leaned to a safe settng but maybe not. Deakin advocates
knowing for sure. Seems like good, albeit expensive advice.
