I'd like to know if I am the only one seeing this. For my particular search keywords Pre-panda my site was at number 3. Post Panda the site fell to number 9. However, I have noticed that while I am logged into Gmail, Adsense or any other Google account my site shows at Pre-Panda - number 3. The instant I log out and check the search terms it's back to Post-Panda. I'm sure their is a reason for this, but I have yet to figure it out.
