 Out-of-order packets SHOULD be acknowledged more quickly, in order to accelerate
 loss recovery.  The receiver SHOULD send an immediate ACK when it receives a new
-packet which is not one greater than the largest received packet number.
+packet which is not the next expected one. That is, its packet number is not one
+greater than the largest received packet number.  A receiver MAY immediately
+ack subsequent packets after first receiving a packet out of order. A receiver
+SHOULD NOT send an immediate ACK any time there is a gap in the ACK frame,
