 In order to assist loss detection at the sender, an endpoint SHOULD send an ACK
 frame immediately on receiving an ack-eliciting packet that is out of order. The
-endpoint MAY continue sending ACK frames immediately on each subsequently
-received packet, but the endpoint SHOULD return to acknowledging every other
-packet within a period of 1/8 x RTT, unless more ack-eliciting packets are

-order, then an ACK frame SHOULD be sent immediately for every received
-ack-eliciting packet.
+endpoint SHOULD not continue sending ACK frames immediately unless more
