Well, that's an impression I had. At least for blueprints, not for other cards. And I'm not sure about the period; it's only two months that I track all box content, so I don't have a reliable data source yet.

But I really have the impression that there are times when you get quite a lot of blueprints for one car and other times when you don't get any.
