Please don't build strawmen like that, especially when you clearly have no comprehension of basic statistics. Even if NPD has 70% of all sales tracked directly, and then only estimate the other 30% through statistical estimation techniques, they can be up to 30% too high, or any (legitimate) percentage too low in their actual figures - statistically, it's unlikely to be that far from right, but unlikely doesn't mean impossible.
But then, if you paid attention, I pointed out that NPD isn't perfect, and that the source we're using certainly can't be called a perfect source. My main concern is that all of this comes from "Aquamarine", who is *not* the one that usually leaks NPD numbers. When Nintendo or NPD provide numbers, I'll accept it. In the meantime, I stand by my criticism - it seems to be putting Sony numbers higher than any other source seems to suggest, and other systems' numbers significantly lower. And some of them are marked as approximate when they couldn't possibly be approximate in an actual leak - they would be specific figures from NPD, not estimates of NPD figures.
