This is probably well defined somewhere else, or blindingly obvious in some manner but on a Monday I just had to ask.
Would construction time for a ship improve if it were built in a larger shipyard? For example, it takes about 84 days to build a CR-90 in a Shipyard 1 with the "optimum" number of NPCs. Would it take less time to build it in a Shipyard 2, for any reason? There are enough unknowns in the equation that I am not sure.
