Just started using it but the count is not really 3 views per ip because sent 57 views and counted 22.. CPM is okay but if it pays only for 1 view then i think you need to have a bit high cpm or allow more visits.
How did you send these views? Did people click and open the link? If so then they should all count since that is quality traffic. Aside from the 3/day limit. Depending on how you sending traffic is may only vount a small %. You need to look at the effort you made for those 22 views. Depending on your method that 22 out of 57 may actually be pretty good.
