Wait Stephen,

Jay do you compared your changes with the expected results? I mean did
you run tests that the Markov chain model is _now_  working correctly
(in all states)?

The setup will be easy: send 10000 packets, capture the packets and
'wc -l tcpdump -r trace.pcap' and compare to the expected number of
packets for a given markov state setup. Enough bugs here where the
should be no bugs at all. Some simple tests should be enough to get
rid of them.
