 If the result is smaller than the min_rtt, the RTT should be used, but the
 ack delay field should be ignored.
-Like TCP, QUIC calculates both smoothed RTT and RTT variance similar to those

+A sender will commonly receive ACK frames that acknowledge larger packet numbers

Please add text on why this is relevant.  Suggestion "that increase largest acked and therefore generate an RTT sample."
