I am become Death, Destroyer of the Worlds. Tremendous accuracy.

"I am become death, destroyer of the Worlds."
Well, after some time I've created finally decent BB, some sort of offspring out of HMS Orion making sweet sweet love with HMS Neptune.
On the first eye glance, nothing special, 1914 British Dreadnought, ~36000 tonnes displacement, 6 twin 343mm gun turrets, 2x2 superposition, 2 echelon, 22 knots, the only special thing 100% veterans. 
I've started 3 battles in a row.
1 BB vs 14 DDs
1 BB vs 6 CL
1 BB vs 5 CA
19,000 meters, morning clear skies, all of enemy ships were decent as well. 
And 2 of these battles lasted ~25 minutes on ingame clock, and the one against DDs around 45 min on ingame clock.
Most of these engagements were fought on distances ~7000m (initial ~11000m, lowest 4000~5000 against DDs), and as you see I was able to pull out accuracy even as high as ~94%, and overall ~60% which to my mind is just waaay too high. So my question is: Should it work this way, or is it some kind of a bug?
