Cornwall, I think your "relative performance" concept is really on the money. There are just two many ways the data can get messed up with the limits of current logging and analysis technology, at least as practiced by most sites.

So what's the answer for more accurate logging? Cookies that are checked on every page? What percent of users have cookies blocked? Session control & tracking?
