I thought this sentence indicated it was 25ms until a value is received: "The maximum ack delay is communicated in the "max_ack_delay" transport parameter and the default value is 25ms.", but I agree it could be clearer, ie: "and the default value and the value prior to receiving the transport parameters is 25ms."?

As a related point, I think it turns out the max_ack_delay doesn't come into play until the transport params are available, because "crypto packets SHOULD use a very short ack delay, such as the local timer granularity."
