[tor-dev] Exit relay proportions for test network

Quick question for all of you. At this stage of construction on a private tor network, I've reached the point where I can't quite figure out how many of our relays ought to be exit relays. I know that a 25 node network ought to have 4 authorities, 16 relays, and 5 clients, but is there a minimum required number of exit relays?
