I realize that the carb is a little richer at full throttle, but I can lean to a higher peak EGT at half throttle than I can at full throttle.

The EGTs on my O-200 also drop at full throttle. Since I fly high altitude all the time (including take off), I always lean for best performance. When I reduce from full throttle, the engine will run a little bit rough until I enrichen the mixture a bit.
