Everyone else posts the CB web view of their Stats, but you're overlooking the really interesting .csv view.
You can download the file, at will, and look at them in a spreadsheet, as above...
I fetch them via a PHP script file_get_Contents($url), and analyze.
So you want to sort on User ID, and compare the dates.
You can also sort on the "Track" field, to see which of your programs is doing the trick. Remember, the Track variable is free for you to set as you want.
The .csv view is how you analyze sales. The web view is Hits and Registrations.
