Basically true, but the FAST magic is useful even in a single message if the messages contains Sequences (FIX repeated groups) CME takes advantage of this in their one message/packet UDP feeds. It is important to note that you have to reset the decoder (clear the dictionaries) between each packet due to the possibility of packet loss.
