Hsie,was just watching 5 torps set at 4m depth and only one stayed there.The rest went DEEP and so I RTFM and found that you put failures to 25mdepth.Isn't this too harsh?Depth keeping issues should mean instead of the requested 4m you get 10 or something less severe.If its set to 10 then the games physics are taken into account since if the draft is 6 and you set for 7 magnetic you will miss.If the draft is 6 and you set for 5 impact and you get 10....you still have a chance to hit a boat behind it with a lower draft.Just asking.
