The article is rather difficult to follow, but as far as I can tell he 
claims that Vbg and Vmr (max range) are the SAME.  But there is an 
obvious inconsistency in his definition of Vme (max endurance speed): at 
one point he quotes "reference 2" which (without explanation) gives Vme 
as equal to .83 Vmr, but he later gives "Vminpwr" as equal to .76 Vmr.  
He gives no explanation as to why Best Endurance does *not* occur at the 
point of Minimum Power.

IMO, the article creates more confusion than answers, and probably isn't 
worth further consideration.
