Based on the activation rates of destroyer-exclusive cut-ins such as “Shu-Gyoden” and “Gyogyosui,” this calculates the probability distribution of how much damage will be dealt to enemy ships.
I created this because I wanted functionality that wasn’t covered by the Operations Room (Update 03/05/2022: It appears the latest version now supports this, but I’m keeping this here because I personally want to see the cumulative damage distribution when there are multiple Critical Hits).

I wanted to calculate night battle firepower all at once as well, but I gave up on that.
I think the quickest way is to use the Operations Room or similar tools to calculate values that include modifications and bonuses.
Please enter: Base Attack Power = Firepower + Torpedo Power + Modification/Enhancement Values (Night Battle)
You can enter a level, but the calculation is set up so that skills like “Fish-Fish-Water” activate even at levels below 80.
Since it’s unlikely any destroyer will reach the firepower cap, I’ve ignored the cap adjustment.

Even if the equipment configuration is "Torpedo-Torpedo," you can still enter the D-gun mounting status, but the calculation results should remain the same.
Refer to the wiki for type coefficients, etc. I’ve seen the theory that the attack rate for "Torpedo-Torpedo-Water" is 1:5, so I’m using that for my calculations.
Calculations are based on a 15% critical hit rate and 1.5x night battle attack power when a critical hit occurs (see wiki).
Since the product of “number of trials” and “activation rate” is rounded down, the total displayed activation rate may not strictly equal 100%.
This calculation does not account for hit probability; it simply shows what happens when a hit occurs.
Because enemy armor random numbers are handled using random generation, results may vary slightly from calculation to calculation even under the same conditions.

I think there are quite a few bugs, so if you could contact me via Twitter (@rityousituraiyo) or similar, I’d like to address them to the best of my ability.
