I've read that VGC adjusts its figures when official numbers are released, so I'm curious...  Has anyone kept track of VGC's accuracy over time?  I'd be very interested to see a comparison of VGC's estimates vs official numbers.  If anyone's been tracking VGC's numbers before adjustments, it may be possible to create a line chart showing a margin of error.  Does that make sense?

*searches*

Here... something like this...

 

 

Rather than exact numbers, the idea would be to show estimates as a range of probabilities.  And by tracking how closely VGC's predictions match official numbers over time, that range may even be narrowed (or, indeed, widened).

It's just a thought but it's something I've wondered about for a while.

There are some people that post pre-adjusment and post-adjument for the week, maybe someone have historic data... and probably ioi have the information backed up for all weeks and how much adjustments he made... some mod may know it... try to talk to Axumblade or Smeags.

NPD threads usually have it.

They have the VGC numbers before NPD adjustments (done like one week or more later), but there are some cases that they take 6 months or 2 years to correct (like X360 numbers) or some that they correct a week later and don't get exposed in the NPD thread (besides that being USA only)... but it helps a little at least.
