No sales number are available.  As the article says, this is based on
publicly available weekly top 10 sellers lists.  We just rank games based on
how often (or high) they appear in the weekly top 10 sellers list.  There is
no new data here. You could always see Real's top 10 list on your own. But
it gets more interesting when you look at 200 weeks worth of top 10 lists
and summarize them all.

Am I missing some way to use the site to get actual sales #'s?

I thought the iWin article by CJ Wolf was useful in several ways and 
appreciated the simple breakdown of earnings per download.  His opinion 
that we shouldn't drift towards a price war and to find more ways to 
calculate the most profitable pricing were well done.

Happy game makin'
