(Edited) Using Amazon isn't entirely accurate to judge NPD sales. Here's why...

Confirmation Bias.

As of now, the only thing you can conclude is that a higher position on Amazon is likely to correlate with a higher NPD position since NPD is a retailer survey and Amazon is a Retailer.

I mean how exactly do you make the calculation in the following claim: "These 9 positions between the 2 in the top 20 should translate more than 40k between the 2 for the month." Unless you can reliably predict Future NPD results given Amazon ranks within a margin of error, then you haven't proven anything.

Not to mention you cannot make any reasonable conclusion about buying trends or habits with simply one month of data, use that conclusion to frame what occured in software, and then use that data set to somehow explain hardware, despite the fact that we can already assume that the correlation between hardware and software is not very strong considering the ratio is not one to one.

I wrote it from a subjective pov and said it from my own personal experience and used words like "should" intead of "will" etc. So no need to get on your high horse. I made it clear also.

And even though I used one month of data, I've noticed it in other months. But to start dragging in data from other months will take forever.

Take the theory for what it is. And yes I do think that if the data was a true representation 9 and 18 should equal more than 40k when upscaled to total sales from all stores. that 10k a week difference and when we assume that Amazon, having a guess, has 25% of gaming releated sales, we are talking about 2-3k difference from amazon. 2-3k difference a week from the largest store in the largest market should be a lot closer in the best selling rankings when you consider how many units the items in the top 20 are shifting.

You gave a theory, I countered. Whether or not it is subjective or not does not make my criticism any less valid. Just because some people had the opinion the world is fact, doesn't mean it can't be criticized.  No high horse, just basic common sense.
