weird stats

i use reinvigorate, which is the best site traffic analyzer ever, and it's free, and in the past 11 hours i've had 35 hits (which is very high), and only 4 unique hits. someone is checking my blog very frequently. but my referrers are only showing links from google searches for "lists and diagrams" and links from yahoo mail, which means it's matt, bored at work, and can't remember the address for my site. what's going on?
