A week before TFM release, this was TF's position in MediaTraffic....


The week it got released the charts now look like this...

Notice that the previous position it got for TF(M) showed 25, the position of TF last week. Meaning the sales for TF and TFM were combined in MT except for the special US edition since it is a stand-alone EP.

While in MusicCharts' chart we see this during the release week of The Fame Monster:

A separate chart for TF and TFM, which means MusicChart did not combine TF and TFM sales unlike Mediatraffic...

That's why in the long run Mediatraffic has higher sales for TFM than Mediachart...
