You can try to approximate the latency by just looking at the number of

packets each protocol sends (both ways), ignoring packets that are just 
empty ACK's.

Btw, the reason you should ignore empty acks is that they happen when you 
have a nice streaming one-way thing, because the TCP rules say that you 
should send an ACK every two full packets minimum, even if you have 
nothing to say.

So empty acks really approximate to "streaming data", while packets with 
payload _could_ obviously mean "nice streaming data going both ways", but 
almost always end up being synchronization discussion of some sort.
