My problem with the Batch Numbering System is that it becomes unwieldy with a large number of different ships produced. The 1700 series assumes 100 ships of that class, if production was only 12 then you have a bunch of unused numbers. Same thing goes if it is based on what shipyard creates the vessels- after 100 you are stuck again or have a new number assigned.
The numbers we have seen are just all over the place- I tend to think they are generated by some bureaucratic process and have little to do with the type of ship, where it was produced or when. Some ships take longer to build, some shipyards are bigger and more productive and while some ships may be created in vast numbers others may be limited runs due to specialty. Trying to figure out which ship came before the other one by registry number gets you nowhere since the show/movie creators were not following a specific pattern themselves.
