Ok I have made adjustments using the rough VGC = .90 for NPD comparison formula. Im editing the % now.

You just used the 90% formula on numbers that were already reduced. So your first post was correct, VGC had huge overtrackings for March.

See the NPD preview, clearly, these are US-estimates: http://news.vgchartz.com/news.php?id=7761

It's also stated clearly in TheSource's first post in this thread.

Then its just confusing in general. I see no reason why VGChartz cannot give explicit U.S. numbers. I suspect the reason for the combination is that it gives a little more fudge factor for the numbers because they can always say the split between the U.S. and Canada/Mexico changes and it differs for different products.
