It's kind of funny with all the arguments about LOP operations that this standard leaning method taught in Cessna 152s, 172s, Cherokees, and just about all other primary trainers without an EGT gauge results in LOP operations.

And is actually approved by the engine manufacturer.

It probably doesn't on most of those planes because most of them are carbureted.  They tend to get rough while still ROP.  I have a buddy with a TR182 (carbureted) who does have an engine monitor (930) and that technique puts him somewhere around 75 ROP with CHTs up around 425.  He flies it that way because it's by the book and what he was taught.  Lycomings seem to absorb that sort of punishment better than Continentals, at least.
