Ah, yes. There was a time when they could reasonably expect people to get on and off a boat quickly enough to reach that figure.That number comes from how many boats are dispatched in an hour. A boat on IASW can hold 16, which means you'd have 187.5 boat dispatches per hour. To reach that amount of launches, IASW requires a dispatch interval of 19.2 seconds.
Today's people, however, for whatever reason, seem incapable of doing so.
But my point was in comparison to Tron, for which I've seen estimates running from just under 1,000 to just over 1,600 per hour.
