I learned a lot about postbacks from reading 
@Landingtrack 's Guide here:

I still haven't figured out how to get the revenue to show up from 
EvaDav into my tracker, but I'm still trying.
As an update, I found from my numbers that IT and DE are tracking at about $0.36-0.40 RPM, so I set my SmartCPM bid at 0.30 on 
Clickadu since theoretically, I can still make about 20% ROI. The numbers have been holding up this week, so I'm going to let it run for a while and see if I can replace my income.
