Does VGChartz adjust sales figures after the real numbers come out?

[NJ5]

For the European numbers, they're corrected whenever facts emerge which prove there was an error. However, errors are few and not that significant, and there have been many news articles also proving that vgchartz's numbers for some European countries are quite accurate.

All things considered, vgchartz's numbers are already very good, and getting better every day.

PS: I should mention that there has been undertracking and overtracking for all the consoles, which means that so far, no bias at all has been seen in the numbers.
