For that to be true, there would need to be no significant variation in power across the attainable mixture range ... which just isn't the case, especially for those engines capable of operating significantly LOP.
Ahah - I left out an important phrase it should be 'Mixture has nothing to do with
best endurance speed.
The reason I (and probably you and IO) keep banging on about it, is that mixture is hugely important in getting the most HP out of a KG of fuel. In this context I need to beg to differ with Pace - in piston aircraft mixture can move specific fuel consumption 30% or more. This is by far the most significant factor unless winds are exceptionally strong (when as in the case posted by Pace he would have been much better off down low - with regard to range), or you are going to really drone along for hours near Vbr (which is very slow)
