In the end all that really matters is that the site is as accurate as possible. I have no problem with adjustments but I think the real issue here is the timing of it. I'm not saying that Nintendo, gfk, Chart Track, or any of the other tracking agencies are wrong but I would imagine that from a raw data standpoint it would be best to wait until you have all the information you can possibly get to have the clearest picture possible before you start recalculating things. Even if Sony's report ends up changing nothing I still would think that it would have been best to wait for all of the big 3 to report before doing adjustments. This isn't the first time I've mentioned this.
