I believe this is exactly what you want to know. I registered the CP program right on the day I participated Epinions, which is the very end of the last century. But since I didn't participate Epinions seriously until the early March, I didn't touch this program until the mid March. As the matter of fact, this amount is roughly the same as the money I have earned with base royalties plus income share. I am still working on the promotion of my content partner site.
Some strategies are very successful.
Others are not. When I finish organizing what I can advise, I write some articles for your higher income. Please be patient. When you create your CP site, you might want to customize it. Please check the following page, if you need to.
