 After the handshake is confirmed, any acknowledgement delays reported by the
 peer that are greater than the peer's max_ack_delay are attributed to
 unintentional but potentially repeating delays, such as scheduler latency at the
-peer or loss of previous acknowledgements.  These delays could also be due to
+peer or loss of previous acknowledgements.  Excess delays could also be due to
 a non-compliant implementaton.  Therefore, these extra delays are
 considered effectively part of path delay and incorporated into the RTT
 estimate.
