Chamber turbulence also changes flame propagation rates and this varies with rpm. RPM advance for MBT does not change in a linear fashion with rpm, in other words, you don't double the advance if you double rpm. Detonation margins usually increase above torque peak rpm as well because peak cylinder pressures are lower.

I have fuel flow on my RV. To run LOP I just pull the mixture (big pull) to 7.4 GPH
after establishing 2380RPM @ 25.8 MP (or WOT if I'm too high to get 25.8). I do not peak from the lean side at all, because I have already established that this flow is well LOP and well outside the "Red Box".
