You have repeated a few times that the manufacturers recommend running the engine at the absolute worst mixture setting. But you keep overlooking the important caveat that they recommend full rich at power settings above 75% and only recommend leaning to best power at 75% or below where they have demonstrated to the FAA that the engine will not detonate with that mixture. Misrepresenting the manufacturers advice may play well with the APS audience but it does not invalidate the true recommendations of the manufacturer.
