Stuffed Tracker does its best to accurately identify all tracking requests. If your site was visited by several people coming from the same office with the same IP and even the same browser -- Stuffed Tracker will still be able to identify them as different visitors thanks to cookie-based tracking.
At the same time, if some of your visitors deleted the tracking cookie or specially instructed their browser not to store the cookie at all, then nothing is lost. IP-based tracking will kick in and there is a very high probability that such visitors will still be identified correctly which will allow you to see their complete paths on the site.
