Nope, not arrogant, just pointed out that it's not fair to compare their VII to PMA VII, let alone call PMA VII "conventional VII."
Regarding their new ester base stock, that's their business -- to make (new) synthetic base stocks -- and the article is a marketing ploy to promote it. If someone uses that new ester base stock and increases the VII content to do so, it's their choice -- it's always a compromise between fuel economy and other oil properties.
