Therefore, the saved RTT and BB values should be the RTT and BB near the end of the connection rather than earlier in the connection.  This might require that the values be save (and possibly sent in a BDP_FRAME) multiple times as things change.

I think it would be helpful, for all of the phases, to put pointers to the sections which have more discussion about them.  (Or maybe a blanket pointer to Section 4 for more details at the front of Section 3.)
