That's a fair point, and one of the reasons I posted this as an RFC. I'd basically like an `obviously bogus' value so that people don't think `hey, my CPU sure it slow' and instead think `looks like this really is a bogus value after all'. However, you're probably right that there isn't a number which can convey that information properly, so how about we just put a string in there along the lines of "not reported" and leave it at that?
