I hope you don't teach math. There are so many things wrong with your calculations that I don't know where to start. The only number that matters is the number of Dis'ers on a cruise. It could be anywhere between 1 and 475,000 assuming that the latter number accurately reflects the total of current and past registered users. Those cruisers could be first time or repeat customers. You assume that Dis'ers are always repeaters because they must be drawn from the 33,250. Dis'ers can be any one of the 10 million. And the 7% calculation is fiction. There is no way to know how many Dis'ers are on a ship at any given time based on the relative activity of this subsection of the Board as compared to the Restaurant Board. The simple math is that at any given time there are roughly 12,000 people on board
DCL ships. And there are (according to you) 475,000 past and present users of Dis Boards. Your guess is that at any one time, 120 Dis'ers are on the 4 ships, or 30 per ship. The Meet and Greet and Roll Call activity and Fish Extended participation levels suggest that you are aiming way too low. If you assume an average family size of 4 people per family, that is fewer than 8 families per ship. Every person who participates in the Fish Extended fun and every person who goes
to Meet and Greets knows about these Boards. That is how such activities get planned. And that is more than 8 families per cruise.
