I read somewhere that the contact switch is allegedly reversed. Therefore your contact shots are possibly contact influence shots. There could be a bit of premature detonation and the shots are exploding some distance from the hull side.

As a test, I did not switch my shots from contact influence to contact as I normally would, and it seems that I am scoring bigger hits, if you get what I mean. More damage, holes in the hull; not always but more often.

Also, I tried a contact shot with the torp set 3 feet below the draft of the hull and it did explode. I followed this torp to see what it would do. It was in fact below the hull when it blew up. That ship only took the one shot to sink. This would seem to confirm the reverseal of the switch.
