| ioi said: krik, the problem is that the only reason NPD is official is because they have no competition. They are not an officially recognised government body or anything, just the best option we have had until now. I hope you (and everyone else) sticks with the site. If shipment data and other indicators suggest we are too high or too low for a particular hardware then I will be sure to make adjustments. Sony's numbers are quoted as being sell-through to consumers, so I think it is a fair comparison. I'm don't think Sony's numbers are right, but I am using it to illustrate that large discrepancies can occur (look at Famitsu vs Media Create Wii sales last 2 months). |
NDP is official because they have lots of market data and make a business selling the data to businesses. They must be accurate or their business goes down the drain. Can you say the same thing about this site?
What do you mean shipping data and other indicators? Do you mean the manufacturer shipments to retail? For that to be a viable option you need to do that all the time on a periodic basis but if I remember it correctly last time you adjusted your numbers (mostly up) was based on NDP's data. Am I wrong? I remember the updates and I think it was about the same time the NDP data come out but I don't know what data you used to do the adjustments. Maybe you can refresh my mind? What source data did you use to adjust your own data 4/5 weeks ago?
