I agree that the sample is too small to give any definitive results but it is a good topic. Having served onboard both an AR and AD (WW2 class ships in USN), they were very often used at forward deployed ports, often those big atolls. They were capable of doing several hundred individual small repair jobs simultaneously as they were literally floating machine shops with around 1000 hull technicians, machinery repairmen, welders, shipfitters, enginemen, electrians, boiler technicians, gunnersmates, etc. Their efforts would be more useful in real life at a port WITHOUT a shipyard but I don't know if this is reflected in the game. I intend to build LOTS of AR's and put them everywhere my broke ships are.
