The first one: 20 cm/50 (7.9") 3rd Year Type No. 1

After 1930's modernization: 20 cm/50 (8") 3rd Year Type No. 2

Furutaka's first guns (Type 1) has a fire rate of less than 2 rounds per minute per barrel. That means with her 6x1 layout, at maximum she only could deliver 12 rounds per minute. Compare that to Nachi. Same guns, with 5x2 layout, but apparently it has a fire rate of 5 rounds per minute per barrel. That means at maximum she could deliver 50 rounds per minute. As for the train rate (turning time) they're pretty much equal.

Why the difference? If you read the first source carefully, Furutaka classes originally was supposed to have the same fire rate as the other ship with the same gun type. But, Furutaka classes had a very complex ammunition supply system which reduced their effective rate of fire. Moreover, moving the shells and charges requires a good deal of manual labor, which means they can't sustain their maximum fire rate at longer period, even at 2 rounds per minute per barrel. Also, Furutaka was commisioned 2 years ahead of Nachi, so the experience the Japanese gained from Furutaka was fixed on Nachi and subsequent heavy cruisers after her, thus their better performance. After the 1930's modernizations though, all Japanese heavy cruisers have the same fire rate and train rate (turning time) on their guns.

As for WoWS, i think they're pretty accurate, but they had to do some balancing too. If not then at some point one nation's warship would dominate the other nations warship of the same type and tier.
