What are VGChartz' sources for weekly US numbers?

Yes, but obviously the npd numbers have an order of magnitude lower error margin (as far as I understand it they have numbers from 60% of the market or something like that). And as I also said previously, VG-Chartz accuracy may be enough to warrant some discussion around the numbers, but don't assume they are correct numbers, since they could very well be off by a significant amount.

I don't think anyone assumes that the numbers are 100% accurate, but Vgcharts tries to get these numbers as accurate as possible.

Also this is the best and most indepth website on sales figures for videogames. No other website even comes close, so really if someone can find a website that offers what they do, and more accurately then please do provide a weblink.

Well, my guess would be that some people actually do assume it is correct :)

I agree that it is a good website in that regard, and there could be some good discussions on the forums. I would personaly change some things around to make it more clear what it is about and change some other stuff too :p

But I'm not gonna try to tell anyone how they should run their web-page.
