If what has been said here is true -- if we never see the NPD quarerly data -- we have no idea what adjustments are made.
Meanwhile, everything VGChartz does is seen by all.
That leads to (mis)perceptions about accuracy.

I am Mario. I like to jump around, and would lead a fairly serene and aimless existence if it weren't for my friends always getting into trouble. I love to help out, even when it puts me at risk. I seem to make friends with people who just can't stay out of trouble. Wii Friend Code: 1624 6601 1126 1492 NNID: Mike_INTV |
