Id be interested in knowing more detail on what kind of sites (tgp, gallery, free sites, etc) or types of programs you are pushing, such as niche or general traffic.
I was just going through my numbers yesterday for the year and I looked at bought traffic and my ratio was about 1:1.2 which is the worst its been by far, so much so that I canned the process. The last few months its been about 1:1 across the board from plain old hardcore to micro niche sites.
good luck and post some stats
