have you all heard of the mj12bot? Just found this is spidering all of our nofollow links which explains our strange increases in traffic at random times of the day
I'm glad you figured that out - but it's far from the only bot out there. In fact, there are alao a lot of human traffic sources that have nothing to do with Google.
If you are trying to understand your site's relationship to Google Search, then you need to isolate only that traffic in at least one report. When I say it that way, it sounds plain obvious, right?
