Messages such as TD berth steps are high-volume, with messages rates reaching over 60 messages per second during peak periods. To ensure these messages are sent efficiently, they are batched in to a JSON list in groups of a maximum of 32 messages, and sent a maximum of every 5 seconds.
In the worst case scenario, a message will be delayed for just under 5 seconds in a quiet period.
If no messages are to be sent in a 5-second period, then no message will be generated.
