You have certainly done your homework here as I am not disputing any points you highlight, actually none. At least you are honest, whereby the majority believe in fairy tales or ghost stories. It is of no surprise that 'all' internal parts, including erector systems and glass are subcontracted to the Indo region of Asia, even Leupold. Leupold assembles the scopes in Oregon, thereby "Made in U.S.A.". This facet is well known to us. Meaning, 'Made-In'> 'Really means zilch, nothing', yet some believe that a better product is being made.
* The bottom line, all scopes basically have the same internal mass, although some may differ on the specifics of the erector system. The quality of the glass is namely of the coatings used as I have received an abundance of differing opinions regarding that issue. G.P.O. claims to have 'Double HD Glass'; 'Whatever that is'. The reality is that one pays for the (1) Name (2) Country of origin, irrespective of the parts. (3) Glass- Schott, as you make mention and 'everyone' seeks to have champagne taste in using beer money-"Does not work".
So in the end, you are absolutely correct with the numbers as referring to sales. We would believe, 'that's just the way it is'. Corporations are in business to increase their profits any way they can and to enable the masses with strings of diatribe in golden fashion.
