Warship guns have the so-called "Same-day maintenance"

Naturally, even when aimed at the same angle, shells won't fall on the same area every time.

Of course, there's the wind direction and wind speed.

But there's also the temperature, the type of ammunition, the age of the gun barrel to take into account.

All these calculations are done on paper.

For example, corrections of the length of three heavy cruisers are not unheard of when you consider that in the actual life firing by the Ise, corrections of up to 600m were needed despite the first volley bracketing the target.

Therefore, I need all ALL your data from today!! Please tell me the color of your panties today and how many times you went to the toilet yesterday or else I can't calculate it!

That's definitely not needed! I'll never say it! I'll fire you lot!

You can't do that, those guys are experts!
