So I've been working for several years on some essays about the conjectural classes from the Encyclopedia, and I've finally finished. The whole thing actually consists of four parts: The Conjectural classes essay. A chronological timeline of starship registries. A batch number timeline of starship registries. And a ship construction estimate spreadsheet. (Batch numbers on p.1, chronological numbers on p. 2) All of this is of course, my own opinion, and any errors are my own. I hope you enjoy it.
