On the subject of range, here is the original travel table
of SMS Kurfürst Friedrich Wilhelm (Brandenburg Class).
At 7 knots, after 4690 nautical miles (approx. 8686 km), 1005 tonnes of coal were fully stocked, corresponding to just under 28 days.
At 16.5 knots, the bunkers were empty after 1572 nautical miles (approx. 2911 km), i.e. after 4 days the ship was no longer ready for action. The situation was similar for the British. Unfortunately, these facts are not taken into account in the game in the event of war or when monitoring the sea.
