This is where Kadar's loop starts. Anything above zero means some of your installs were produced by your own players, and your paid installs carry a lower true cost than you paid.

D0 D73 D146 D219 D292 D365 cumulative net revenue
Cumulative net revenue per install against your true cost per install, over 365 days. Computed from your inputs in this browser.

Kadar fits a curve through those three points, integrates it forward to 365 days, and compares cumulative net revenue per install against what you paid for the install. Everything is computed in your browser from your numbers. None of Kadar's fitted parameters are used here.
