Except for the fact that we have YEARS of data of this not being the case. For example, at one point in december Gamecube was on Amazon's best seller list ahead of the Wii, 360 and PS3.

It of course did not chart on NPD.


And of course... From Amazon's website itself...


The Amazon Best Sellers calculation is based on Amazon.com sales and is updated hourly to reflect recent and historical sales of every item sold on Amazon.com.

"While the Amazon Best Sellers list is a good indicator of how well a product is selling overall, it doesn't always indicate how well an item is selling among other similar items."

he's not looking at the hourly charts.   he is looking at the monthly charts.  a monthly average is bound to be more accurate than an hourly average.

Except it's calculated the same way.   It's not actual total sales.
