Steve, Even tho you can get higest RPM at full throttle by leaning, I think it is proper to leave the mixture at full rich for max power climb. This additional fuel helps cool the engine parts --valves, etc at full power....and is considered necessary to prevent burned valves...
Now, if you lean at 3/4 throttle, to get best RPM to compensate for high altitude airports, then you still get the additional rich mixture at full throttle, while proper mixture for the altitude adjustment....The economizer valve (rich mixture ) only operated at full throttle openings.
