Thing is, at 100% Realism (map contacts on, though) I just sunk 7 merchants ships for 60,000 tons in Bungo Suido - with Mk 14 torpedoes. On my first patrol, in December 1941-January 1942 with FOTRSU.
That's insane. I feel I am cheesing something somewhere because while yes, the majority of these were large tankers, still I shouldn't be having such a Happy Time so near Japanese waters in December 1941. That is why I am considering starting a new patrol but with map updates off.
