As an author--and therefore, by definition, insecure--I often check Amazon ranks on my novels even though I know that said numbers are pretty much meaningless.
How meaningless? Well, when the stock of certain books gets low, Amazon will say "Only X left in stock." So occasionally, it's possible to track how many books they sell over the course of a few hours.
I've seen the sale of one book knock an entire digit off the end of a book's sales rank. They're that fluid.
Bottom line? WotC doing well or poorly, Paizo doing well or poorly, Amazon's numbers prove absolutely nothing.
