 ## Generating Acknowledgements
 QUIC SHOULD delay sending acknowledgements in response to packets, but MUST NOT
-excessively delay acknowledgements of packets containing frames other than ACK
-or ACN_ECN.  Specifically, implementations MUST attempt to enforce a maximum
-ack delay to avoid causing the peer spurious timeouts.  The RECOMMENDED maximum
-ack delay in QUIC is 25ms.
-An acknowledgement MAY be sent for every second full-sized packet, as TCP does
-{{?RFC5681}}, or may be sent less frequently, as long as the delay does not
-exceed the maximum ack delay.  QUIC recovery algorithms do not assume the peer
-generates an acknowledgement immediately when receiving a second full-sized
+excessively delay acknowledgements of packets containing frames other than ACK.
+Specifically, implementations MUST attempt to enforce a maximum
+ack delay to avoid causing the peer spurious timeouts.  The maximum ack delay
+is communicated in the `max_ack_delay` transport parameter and the default
