Because ioi doesn't think they're right. There's nothing more to it than that.
This site is far more credible than any other because people know where this figures come from. NPD is a big profesional tracking institution and they are always right in such situations. With all respect to every single member of the crew and especially to ioi but you just can't pretend as you are right.
Vgchartz numbers were very close generally. Why destroy it all by keeping some wrong figures? Even if ioi is right and NPD undertracked MS on purpose (what I really doubt because they are paid by MS after all) for site's sake he should adjust the numbers. Not a big deal.
Except when Microsofts quartly shipments came off... they were wrong. Way wrong... and VGchartz was closer to right before they adjusted for NPD.
Why would you adjust for NPD for 360 and DS when NPD steered you wrong the last time you used them to adjust 360 and DS?
It's likely NPD's tracking math is off, but they arn't going to screw with it until after X-mas because X-mas is the most important time of year, and when changeing your math you can make it better, or worse... you don't know until you get more data. They can't afford to correct their math on the DS or 360 to be more correct until after next year. Ioi is betting that right now his statistical formula is better then theirs... since it did perform better the last time for DS and 360.
Or atleast that's what i think he's saying.
