Yeah, like I said, it depends on the situation - the course, pads, tires, car mass, ambient temp, etc. all affect braking performance. My point is that you can't rule out drilled rotors simply based on mass or swept area.
Anyway, I wouldn't suggest using anything other than blanks on a daily driver, so this is getting a little off-topic.
