 min_rtt is the minimum RTT measured over the connection, prior to adjusting by
 ack delay.  Ignoring ack delay for min RTT prevents intentional or unintentional
 underestimation of min RTT, which in turn prevents underestimating smoothed RTT.
+A sender calculates both smoothed RTT (SRTT) and RTT variance (RTTVAR) similar
+to those specified in {{?RFC6298}}.  Note that smoothed_rtt does for the first
