Hard to say if there should be any adjustment, especially on the software side, since NPD is not the "be all end all" source that some people consider it to be. It doesn't have access to Walmart or Amazon numbers, and while it may try to compensate for that in various ways, personally I am certain this is responsible for much more inaccuracy than people may think.
