Games publishers have all the data you're talking about and much more. They've all mostly experimented with either no DRM on game releases or very trivial DRM, and have models that can predict quite accurately these days what investment into a protection will yield what sort of return.

I'm always shocked by the frequent assumption made by people in the software world that game/movie studios don't know what they're doing financially, despite decades of experience and being the world's biggest entertainment businesses. Of course they know.
