With WebTrends, it seem that the length of time spent on the site can be a very questionable stat. It will often come in around 15-17 minutes on one large site we deal with when up to 50% of the visits are single access sessions. It seems there might be a lot of browsers that end up on the site and then move on to a different browser such that the session stays open and the length of visit gets artificially inflated. The median might be a more accurate stat.
