You know, I have to say that I'm a little embarrassed by some users in this thread. VGC has never claimed to be 100% accurate, ioi has stated on multiple occasions that his methods are based on extrapolation and identifying trends.
This is the way VGC has always done it. We know it isn't 100% accurate, but it gives us a vague idea. Also, for the regions which people actually seem to care about (Japan, US and Europe), we know that two of those three are almost perfect, so where's the issue here? I just appreciate getting the numbers, knowing they aren't completely accurate, rather than getting nothing at all. Maybe that's just me.

That's how I look at the vgcharts. Trends that show xbox is currently falling and PS4 staying high.
