Curiosity about Bismarck: With regard to accuracy of guns (spread). The german gun provide a 50 % ige Längenstreuung (50 percent spread for lenght) at 20 km in the order of slightly above 1% of range acoording to its fireeffect tables. Its ballistic quality was considered as “ausgezeichnet”(best schoolgrade). British artillery observers also mentioned the comparatively high density of german salvos. That means out of 8 shells fired, four would land in a range interval of about 200 m around the MPI (±100 m) that yields into a hitprobability of 22,3% at 20 km if MPI is on target.
