What someone needs to do is come up with something like this:
The more official the better. It'll give us a good understanding of how the ship looks like inside.
Incidentally, I think that shows how it cannot possibly be only strictly 2 decks tall at the rim. The old Connie could barely squeeze in 2 decks there
Still wouldn't shut people up. Even the diagram in you posted isn't universally accepted. We have a official length of the ship, and people are still saying the people that created the damn thing are "Wrong"
