I have acess to Media Create, NPD, and Chart-Track/GTK numbers at work and did some sums for the worldwide 360 sales and the most recent figues only come out to around 19.5 million.

 

I realise why you're not posting the data you claim adds up to 19.5m. Deducting NPD (11.3m) & Media Create (0.6m), would leave Chart-Track & GfK figures at 7.6m. This is just too high to be possible. Truth is it's just not possible to come up with a figure of 19.5m by adding up Media Create, NPD, Chart-Track, and GfK figures. The difference can be explained by sales occuring in many countries not covered by the trackers you claim to have access to.
