iTunes Analytics Opt-in Rate

HI There,


My iTunes Analytics is meauring a 20% Opt-In rate. If on June 10th, the install numbers are 38 units, and then the next two days of retention are 24% and 16% then what would be the total usage really?


Do I simply divide the installed units and the percentages by the opt-in rate of 20%? Thanks!

I'm pretty sure that is correct. 38 units / 0.2 = 190 total units.
