Thanks, Steve. Have another question in regards to this. The ships itself are build accordings to the ABR number - which is different to the Mod Rate.
I have the following example:
Race Shipbuilding Rate: 400BP
Planetary Modifiers: Manufacturing 90,37% - others are at 100%
So the "Shipyard Task Tab" correctly shows 361.5 BP per 5000t slipway.
Wanted to build a ship which has 313.5 BP, so I expected it to be build in under one year. But no, the game says it would need 406 Days. So I checked and when the task is created, in the list of active shipyards it gives the ABR number, which is 277. According to this number I come also to the 406 days. But how is this number of 277 calculated?
