| Brett said: Not as confusing as I do! As I've explained many times - we get data, we extrapolate it, check it with other data then post it up on the site. I expect some differences with other tracking services - it's inevitable - but month after month I'm shocked with how the data NPD releases makes no sense and seems to yo-yo. Some months it is way higher than ours, other months way lower, and for no logical explanation! Sure, no Easter this March, but that maybe has a 5-10% boost at best for the month. And with Halo Wars, Killzone 2, RE5, Pokemon Platinum etc hardware sales just nosedived? We see drops in our data Feb - March, as is normal, but not drops this big. |
As much as I am gonna feel silly trying to tell Brett about tracking video game sales :P
My guess is that the yo-yo-ing could by NPD's form of adjustments. If they find out they overtracked the Wii one month, then they could deliberately undertrack it next month so that their numbers balance out in the long run
