Not only does personalization change things around, but time of day and IP location seem to affect things as well. I think. So I have a site that was ranking around #18. On weekends, it drops down to around #30. Then at some times of day it might rise as high as #16. It's like Google is also creating a time/location model of content. All this stuff with Google is all so much reading the tea leaves, though. Very frustrating. If your marketing consisted of having a few signs around town you could easily go out and count the traffic and observe patterns. With Google, it's much more random and complex.
