Just becuase they dont track a particular retailer doesnt mean they cant factor that retailer in on a mathematical model. I'm pretty sure a larger sample size will usually be better than a smaller sample size though.

I'm not sure what you are getting at here, other than you are obvious unhappy with one of the results NPD have given

Which number is it you dont like?

im not unhappy with any numbers, i just wanna learn more about it and i couldnt find usefull informations on this site or the web.

and 1% sample size is more than enough to get realy good data if the sample is represantativ.

 

I didnt say 1% couldnt be enough.  I said more is probably better... I stand by that.

Manufacturers and others wouldnt pay NPD if the data they provided didnt eventually match their own data from shipments, supply and eventual new orders from retail. 

NPD is as accurate as it can get IMO.

Npd doenst sale just tracking to manufactures, nobody would by those numbers because they could generate those fairly accurate by themself. they buying data about costumer behaviour and other things, thats realy valuable, even if they have problems with some games from time to time.
