I don't understand ,,why isn't he changing it? ,,,what does he have against this ?? NPD data are as accurate as they get,even Microsoft and Sony have approved the numbers today |
Vgchartz is a retail tracking service that is completely independent. This site has it's own retail samples, and they cover about 15% of the market (Note: I think I remember ioi saying that). That's enough data to make exteemly accurate estimates. Ioi does not copy & paste NPD's numbers, as that would defeat the purpose of this site. If there's a huge gap between VGchartz and NPD's numbers, ioi talks to the publishers and other companies themselfs. Depending on what they, ioi may or may not adjust the numbers. Ioi is not going to change his numbers due to another tracking service. He may, however, use them as tool for other things. Just think of it like this: does Famitsu adjust their numbers because of MediaCreate? No, it doesn't work that way. Both have their own retail samples and data to work with; the same is true with Vgchartz and NPD. |
Please, correct me if I'm wrong but I guess it happens because MC and famitsu cover a similar % of the market, while I think this is not the same case. And obviously the more you cover the more accurate you can be
This time NPD and VGC described two totally different scenarios for XBOX360vsPS3 competition and for DS sales. This is what is confusing people.
Last month's data were totally surprising nonetheless.
