By reading through your stats I see that a request is not equal to a unique session. A "request" is a request for a unique element of a page...thus if a page is one html file, 15 jpegs, and 4 gifs....you get 20 "requests" from that page being loaded everytime.
The only interesting number, IMO, is daily/month/yearly sessions, and UNIQUE sessions.
