In my opinion, ignore LOP performance until you have the capability to manually select that condition. Tuning an overall curve for LOP will always mean you are too advanced for best power mixture. The opposite is true of course. Best power timing will be too retarded for LOP. It's the fundamental flaw in the "one size fits all" approach to timing.
You can certainly play with the LOP advance as a knowledge exercise, but call Ross and get a reflash before you try to execute a new curve
