My main questions would be if you're matching the time frame correctly, and whether your factoring in that VGChartz includes data for Canada ... Quite often NPD has odd week overlaps ( a Week in October may be reported in their September data) which could (easily) account for the loss of 100,000 units; and Canadians could account for 50,000 XBox 360 systems sold. |
I am counting the following 4 weeks that NPD are covering for october, since I assume he is doing the same. Haven't taken Canada into account.
13/10 - 151k
20/10 - 138k
27/10 - 136k
03/11 - 138k
total - 563k
Assuming Canada is about 10% of that number then we have around 510k sales for USA, still 185k difference.
