Estimating iPhone App Store Sales From Rankings - update


Here's what the average daily sales graph might look like for the Top 1% to 10% in popularity of all paid iOS app (out of 270,000 paid apps in the App store).

See my April Musingpaw blog post for details on the power law equation used to estimate these sales.  Note that any top 100 app is in the top 0.03% of all apps, which is thus way off the top left of the scale.
