Most pages under 5, battle scripts usually double that depending on the game...
On our game Cypher though that runs a tick every 10 minutes it can sometimes hit up to 300-500 depending on the number of players signed up for missions. Kinda cool to hook up to the mySQL server with there administrator tool and watch the live graphic on the number of queries per second the server is running... That tick hits and WHAM it spikes to the top of the graph.
