Possible to include % uptime?

[Grebbin]

On the server list when you view a registered server it lists details including average players. Would it be possible to calculate the % uptime for a server over certain timeframes, say the last week, month, and lifetime? That way players looking to select a server would be able to see that server A has 75% uptime while server B has 93% uptime. It would also give server admins a clear picture of their server uptime and allow them to use this number as a basis for improvement. Just a thought!
