I will be surprised if the "official" VG chartz number for USA Black friday week is 2:1 Xb one:PS4.
By the looks of the Infoscout methodology the precision of their estimate is worse than VGC. They rely on consumers sending them images of their receipts and there doesn't appear to be much statistical rigor to their. The only thing they have over VGC is that they pretty much get real time immediate results.
As statistically valid sample of the size infoscout obtains would actually produce very reliable results, but their methodology looks amateurish and simply designed to get fast results.
