Average level?

If you're talking about our average level of users we have sign it:
It varies quite a bit depending on the day and the time and also seems to change from week to week/month to month. Recently I think we've been getting anywhere between 2 and 10 people on at a time (from what I can see). I've also seen times when we could have between 10 and 20 people regularly on at a time. In terms of currently active accounts, I'd say that we probably have between 70 and 100 active accounts, though that's kind of a complete guess so I'd be open to other numbers.

If you're asking what the Total Stats average level is for users:
It's probably quite low. There are a ton of registered users and not many stick around for long periods. Since the first couple hundred levels are pretty easy to get, I would probably place the average total level to be around 200~300, not counting all the people who play for 5 minutes and then never come back.

If you're asking what your average level is:
Divide the total level shown in your game client by 8 to get your average stat level, however I don't think anything uses average stat level, just total level.
