Numbers are typically within 5% of other tracking services for a given territory. Where VGC is better than the other tracking services is that we track worldwide numbers and not just a single region.
The two major Japanese tracking firms are routinely 30% different from each other and they are considered "profressional" where VGC is often bashed for a single month where one console is off by 12-15% in the US from NPD.
The basic point is that everyone (NPD, VGC, MC, etc..) is estimating and errors can and will happen. But for some reason despite the fact that we cover a significantly larger market with an admittedly smaller sample we are held to a much higher standard than everyone else. Tell me how that makes any sense?

I just wanted to elaborate on this response and answer some of the specific questions asked by bernadettedv. Sqrl is referring to hardware numbers here, software numbers are a lot harder to estimate and tend to be much less accurate, often off by 50%.
VGC figures are definately better for new games. PS2 software isn't very well tracked and data is incomplete for most games released before the start of this generation.
PC software sales are even harder to track than console software. It's carried by a somewhat different set of retailers and some say the number of online transactions for PC software make any attempt to track it futile. VGC is focusing its limited resources on tracking more measurable console sales.
And for your final question, NPD data costs many thousands of dollars to gain access to, and even if VGC as a free site was willing to pay that price, I doubt NPD would permit VGC to publish their data for the whole internet to see. However, VGC does use what little information NPD publicly releases to gauge the accuracy of VGC numbers.
I'm sure one of the mods on this site will correct me if any of my answers are inaccurate.
