I do think removing the Z would increase credibility hugely

Anyway, the SW data is more dodgy, and the MGS stuff was just 1st day, so in most cases VGC is right. Who says NPD is perfect anyway, I am sure they get things wrong. Tracking is not a perfect science unless you have 100% of the data

 

true, the NPD has been known to scew results to discredit others. that, and they correct when manufacturers shipment numbers are out

I can't remember whether they change past data without telling anyone, or that they add extra units to future months to make up for an undertracking, but either way, they do not keep the public well informed

they lost a case (well settled out of court) quite awhile back where they misrepresented sales data, and caused the stock of a company to collapse. they company in question, had sent multiple letters asking them to correct the sales, (they had been tracking them independently), and the NPD would not change its numbers, despite internal documentation that they were undertracking,  the effected company got hold of the internal documentation when litigating..... the company in question being hurt by the NPD group Apple computer
