It's certainly legitimate to discuss how accurate his numbers are, but it's a very different system from the Bookscan one that Scalzi is criticizing.
Scalzi was specifically references the differences in the hardback sales verses the estimate. His comments about the various streams (paper, ebook and audiobook) are also important, but from a different set of blog posts.

Fine, if you want to say that Bookstat is more accurate than Bookscan, what were the differences in estimate between Bookstat and Bookscan for Scalzi's book? Scalzi references that screen scraping from Amazon isn't particularly accurate in other blog posts.
