Getting up-to-date information from SelectServer V8i

We have just gone live with MicroStation V8i family of products and are using a hosted Select Server license at Bentley.

I need to know at what point I can judge that the usage figures reported are complete so that I can generate meaningful management reports - i.e. how often do client PCs with an activated license send their usage back to Bentley HQ - it certainly does not appear to be every day.

Is there any way to configure the clients to set a particular license reporting interval?

The clients are PCs permanently connected to the network with an active Internet connection.
