I assure you I am very educated, I have a Masters degree in computer science, I am more educated and intelligent than most people on these forums.
NPD just publishes numbers, Microsoft doesn't know how many units they sold, just shipped, so they just took NPD's numbers, and published them on the xbox site, of course NPD numbers are highly inaccurate as VGChartz show.
Education is pointless if you can't use basic reasoning skills.
NPD's tracking is more accurate than VGC. which is why VGC adjusts to NPD. Its literally that simple.
The fact that the numbers were published on the official Xbox Website, is that the accepted them as true. Hell, if VGChartz was more accurate, why would MS use NPD's numbers over VGC's?
Your logic is flawed, being used on the official Xbox Website does not prove accurracy.
That's like claiming that if a false statement is made on TV or shown in a newspaper, it proves it's validity.
For centuries and even now people believed false things, and as science advances they are shown that way.
In a few months It will be shown that I was right, and you are all blind.
It really wouldn't make your arguments or reasoning correct tho, like the people who wear signs which say "the end is nigh" if the world was to suddenly explode would they have served a good life? would it have been by some inside information which made them think they should wear such a sign while sitting asleep on the side of the street?
What this thread boils down to right now is you thinking that if the Xbox 1 was to start selling fast in the US you would have been right, because you looked at some estimated numbers and looked at your computer science degree and added those 2 things together to generate some rock solid numbers of the X1 winning in sales globally in the USA lol it would sort of be like trying to get out a spread sheet full of random numbers and claim that using those numbers you could guarentee that if you flicked a coin you could predict it would be heads.... flicking the coin would make you feel warm and fuzzy inside 50% of the time and the other 50% of the time you would be going back to your spread sheet to alter some numbers.... but there would be no link in reality to your prediction and what was happening.
As for you asking for links to VGchartz numbers being estimated.
Here in fact is a link to Brett in 2007 talking about where the numbers come from and their accuracy(he is the sites creator btw)
and finally here is a link to keep you amused, you should find hours of fun here for yourself!
