There's also traffic data about CoD. I think 2000 is one the safe side. You could probably try it yourself though, and e.g. enforce a high latency through an external program to simulate that someone joins from another country. Than check if the sending of package is stable by sending something easy to debug (like a enity xyz/position vector or some other changing number). Don't know for sure if that will work though, maybe someone else here knows.
