If you really wish to understand how the tcp stack works better and / or fix bugs in it, you really need to use tcpdump to log what is actually passing over the wire. The statistics from netstat -s are only meant as an overview, and are not detailed enough to make inferences about how things are actually working. If you can show specific behaviors in a tcpdump that you're interested in, I'm sure that many people would be willing to help answer your questions.
