I think Jana's suggestions LGTM.

> +smoothed_rtt and rttvar are computed as follows, similar to {{?RFC6298}}.  When
+there are no samples for a network path:

I think @janaiyengar suggestion seems good and slightly clearer than before, though maybe line 361("where rtt_sample is the initial RTT." needs to be updated too?

 ### Handshakes and New Paths
-The initial probe timeout for a new connection or new path SHOULD be
-set to twice the initial RTT.  Resumed connections over the same network
-SHOULD use the previous connection's final smoothed RTT value as the resumed
-connection's initial RTT.  If no previous RTT is available, the initial RTT
-SHOULD be set to 500ms, resulting in a 1 second initial timeout as recommended
-in {{?RFC6298}}.
