AI gunnery skills?

[602Sqn_Puff]

I was wondering how the AI was shaped to hitting with every second shell. Here is the scenario, I was of the coast of England when I spotted a warship , I went straight to peri depth and view her as she approached, an armed trawler, read her info and saw that she could only do 12 knots top speed. Being a brave soul I popped to the surface and ordered ahead flank and weaving back and forth between hard port and hard starboard rudder. Now I was travelling at about 15kts, weaving and was at least 8000m away from her, of course she started to fire at me and after about 3 shots she found the range and I took an absolute battering.Just about every shot found it's target.
[I have spoke to a WWII vet who served on the HMS Cossack { they attacked the Bismark } and he told me how hard it was to hit that ship with the guns....hehe I would say its a little larger than a U Boat]
The AI targeting seems a little too good, has anyone else found this out?
BTW I am now running at 20m silent with me bloody tail between my legs lol
