Bloggs I don't disagree with that point whatsoever. My argument is that the significant speed reduction required to appreciably reduce turbulence effect is not 0.01 or 0.02mach and just isn't available in the confines of coffin corner.
But many pilots seem happy to reduce to or below best l/d speed (green dot on bus) just to 'lighten the load' on the wing. As opposed to trying to maintain mid-point between green dot and red line for max protection from both limits. Call it common sense or airmanship?
Neither is very common now!
