@Inspecta, agreed. The problem is there is no way to judge if trading on VGChartz data results in good predicting as there is no way to ultimately judge the global stocks without NPD, MediaCreate, ChartTrack, and all the other professional firms around the world releasing their data. We don't know the real information for the long term. In the short term, in comparisons I have seen, VGChartz data does not stack up well to NPD data. This would only imply that the VGChartz data is worse as sales become sparser.
But that is all beside the point. The main point is we are not predicting if we are just data mining other sites. VGChartz isn't a prediction site, it just posts estimates of past sales. Copying those numbers here isn't predicting.
The real test of our predictions will be seen on July 19 when NPD provides sales data for the game futures we are trading. This is one instance where we can see how our game predictions stack up directly against "real data." We have been doing pretty well on consoles each month.
