When you link in from here, it's recorded as "incoming" on their list. Then when you scroll down to 170 where UP is and click on that, it takes you back here and is recorded as "outgoing". May be wrong, but looking at the other sites stats, that appears to be the case. I think they are looking at "incoming" as a vote (it drives traffic to their site). Plus the incoming is less than the outgoing indicating that several of the same IP's have "visited" and then left again to the same site and the repeated "incoming" wasn't counted.
