Well, this screams author mill from the start because of the extensive marketing plan required and the number of their authors which is about 200. They have sold 1825 e-books to date, which I assume means series books and trilogies. I don't think the paperbacks have made a dent, otherwise it would listed with their amounts.
Do the math and see how many books (on wide average) each author is selling. Could it be (on average) that the authors are selling about nine or so books apiece? It is rather pitiful but absolutely accurate in the performance of most small presses out there today. I believe most Small Presses have taken a horrific dump in the past three years--of course, that is my experience, but I've seen dozens of other authors going through the same sales slump. I have a rock solid reason why this is happening, but I think I'll use it as a blog topic.
