I would like to make a further point now that I am thinking about it again.
We are trained to richen the mixture when we climb. If you start LOP
and go to rich you may increase the EGT. As you can see starting
with LOP peak is opposite to what we are taught.

Paul, I don't know how you got on this path, because I'm sure you do it right in the plane, BUT I have always LEANED the mixture with increasing altitude.  At least that is the way I was trained!
(less air requires less fuel right?)
 The second sentance of this paragraph, "If you start LOP and go to rich you may increase the EGT.", is EXACTLY RIGHT. That is one of the reasons that most manufacturers don't like LOP operations.
If you are ham-handed about it, or forget to update as you climb, you can put your engine in the detonation range.  IT is true that we are normally taught to take off full rich, unless way above sea
level. Tracy's claim to take off LOP is exactly opposite of what we are taught to do with a Lyc/Conti.

Yes the optimum is where the engine runs the best. You can use the rate of climb
indicator to set the mixture at altitude. When taking off at high altitude airports 
we are taught to set the mixture at max static RPM. 

The table is what happens if you don't change the mixture.

Tracy has so much HP in his airplane is almost uncontrollable if he takes off
full rich :)
