I typed up on notepad also...
Optimal torpedo attack range when submerged is 1000 yards=914.4 meters
Optimal range for surfaced torpedo attack (night) is 2,500 yds or 2286 meters
A lot of the orders will say patrol within 150 nautical miles 150 nautical miles=277.8 kilometer.

Well, hope it does not deter you from running the mod, it will be worth giving it a try. Hope this helped.
