I have a website that has had a decent spike in popularity. It's a real-time multiplayer game, and on average I have around 100 users at once. You can see this if you total all of the first numbers in the "#/#" player column.
The tracking script is definitely on all of the pages. Due to the nature of the game, my sessions are very long (~9 minutes on average). Could that have something to do with it? Also, is this likely affecting my long-term data?
