Managed to hit a 17 knot Royal Sovereign Battleship with 3 eels at approx. 2km with the stock stadimeter last night, though didn't stay up long enough to see if they hit where i was aiming or not, DD snuck up on me as i fired the spread. heard 3 impacts and less than a minute later heard the ship breaking apart. So i can conclude 1 of two things, i've actually gotten used to the stupid thing or my aim under perfect conditions is really that bad
