From what Vordan quoted:I'm wondering about that "lucky number" bit because if 40 "was like 10 books a week", did anybody realize 52 would be 13 books a week?. . . How we got to 52 was an interesting thing, because originally it was 40. Realistically, the math was something like, it was like 10 books a week. There was consistency of what you were putting out there. It seemed like that was the [number] that people would be able to absorb in the course of a week. But ultimately, we needed a little more product, so we pushed it up to 48. I had it at 48, and Jim had it at 52. When I asked him, “why 52?” He goes, “You had a lot of success with that weekly series 52. It seems like a lucky number.” And I mean, when you have logic like that, how do you argue?
