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.

Yes it has been quite weird but NPD is not the gospel of course.  Shipment numbers before have shown them to be way off so yea. 

I think we are in a close enough range to them to be quite satisfied and even some of our numbers making more logic.  Of course I must remind everyone that tracking sales is the science of predicting human buying habits.  You just might get a yo-yo effect every now and then so it is hard to tell.  However, trends over time have shown there to be more method to the madness.  But most of that method can really be seen in the later months of the year towards holidays.  So it's quite possible these yo-yo things will happen but more than likely they will level themselves off to where it follows the normal trend.

 

Yes and theres also something called overshipping =S
