Mediatraffic is the absolute worst, I have no idea why ATRL uses it. Its rule page literally state "We look at the charts of the top 20 countries, then guess what the sales are in the other 200" - Every person in China and India could own a copy of Prism and Mediatraffic would still have it at 3.5 million sales.
The underestimation in the thread title though.
OOTB - 5 Mill
TD - 11 Million
Prism - 6 Million
Total = 22 Million
Fix it.
to go!
