Good post ...
I agree that is another motivation for running at lower RPMs during lean burn.
I only listed one motivation , the change in flame speed... I did not intend to suggest it was the only motivation for the lower RPMs ... sorry if I gave that impression.
Whatever the combination of reasons for it happens to be ... the results are the same ... running the engine at lower RPMs still reduce engine friction ... which is an additional benefit ... and the point I was trying to add.
