VGChartz doesn't track anything. They extrapolate from few samples (don't know how many), historical data and other stuff

This is the definition of tracking pezus.

I wouldn't say that. Tracking is knowing, not estimating. Something like NPD can be called a tracker because it has real data for a huge part of the market. VGC does not.
