@usyk&DMJ: The NPD numbers are official as "official NPD numbers". Just like we have "official VGC numbers".
Since "official" basically means "stand behind them", not some ultimate truth, anyone can enter the market and make as "official" market research as NPD. Then again, "official" can also be "approved by someone", which is context related.
Anyway, the main reasons for using NPD is, that it's the authority and there's no competing company.
