|-|Methodology=
Just how much more important one stat is than another is hard to determine, especially when considering different map scenarios that could strongly encourage one stat over another. 
However, the overall rating of a ship could be estimated with some (somewhat) basic math. 
Each ship class is separated into their basic classes instead of separately, as most sub-classes perform largely similar roles (such as CA & CAV under the CA umbrella).abilities/traits that differ from the norm of their class.
Every ship is scored based on its stats, special attributes/abilities, and class. 
* These small differences are instead handled by awarding points to each ship based on special
** For example, CAVs and Zara/Pola get bonus points for the ability to carry Seaplane Fighters.
* Each class also might place more or less importance on an individual stat. 
** With this in mind, each stat/ship class combination can receive a scaling modifier via a stretch/compress multiplier to each stat on a class-by-class basis. 

|-|Averages=
Each basic class has its stats averaged across the entire class, using the stats from each ships' final remodel. 
* Special versions of the same ship are factored in separately from each other.
** For example, Kaga Kai Ni and Kaga Kai Ni Go both apply separately to the overall average.

|-|Stretch/Compress=
Each basic class also has a stretch/compress multiplier based on an estimation of how important an individual stat is to that class of ship.
* In most cases, stretch/compress values remain at '1' due to being universally important and/or there is enough variety between individuals to already have meaningful differences
** A value <1 indicates a 'Stretch', meaning the stat is '''less''' valuable
** A value >1 indicates a 'Compression', meaning the stat is '''more''' valuable
* Exceptions:
** Fuel & Ammo
*** No scalar multiplier
*** Instead, they have additive modifiers to the StdDev for each class
** '''Ignored:''' HP, Luck, LuckMax

|-|Standard Deviation=
The Stretch/Compress value is applied (via multiplication) to the Standard Deviation of each respective stat for each respective class. 
This Standard Deviation value denotes how wide a standard 'step' is from the average for the class which directly factors into the rating clusters. 

The following table displays the Averages, Standard Deviations, and Stretch/Compress values for each class. 
{{User:Memetails/Averages Deviation and StretchCompress}}

|-|Stat Evaluation Clusters=
Using the above values, each individual ship is evaluated into clusters based on their stats.
The math & clusters are as follows:
{| class="mw-collapsible mw-collapsed wikitable typography-xl-optout" style="width: -moz-max-content; width: -webkit-max-content; width: max-content; text-align: center; vertical-align: middle; "
|-
! Cluster
! '''DistanceFromAvg''' = ShipStat - ClassAvg
|-
! Insane:
|> 2 * (StdDev * Stretch)
|-
! Outstanding:
|> 1 * (StdDev * Stretch)
|-
! High:
|> 0.5 * (StdDev * Stretch)
|-
! Normal:
|< 0.5 * (StdDev * Stretch) '''&''' > -2 * (StdDev * Stretch)
|-
! Low:
|< -2 * (StdDev * Stretch)
|-
! Bad:
|< -3 * (StdDev * Stretch)
|-
! Terrible:
|< -4 * (StdDev * Stretch)
|-
| colspan="2"; style="text-align: left;"| Note: 'Stretch' refers to both Stretch & Compress
Clustering Exceptions:
* Fuel & Ammo: Additive Stretch/Compress instead of multiplicative, table is basically inverted due to lower = better
* Luck & LuckMax: Set values shared across all classes.
**Insane/Outstanding/High/Normal/Low/Bad/Terrible = > 50/35/25/10/5/0/NA
* HP: Instead based on 'good/bad' values via the overkill mechanic, such as %4, %6, %12, %4-1, etc.

|-|Stat & Rating Multipliers=
Each stat is assigned a numerical multiplier based on an estimation of total value/importance. 
Each cluster is also assigned a numerical multiplier based on an estimate of how good or bad being in that cluster is. 
These 2 values are then multiplied together, resulting in the following table:
{{User:Memetails/Stat & Rating Multipliers}}
For example:
* Firepower is generally more important than LoS: '''Firepower > LoS'''
* Night power is generally more important than Firepower: '''Night > Firepower'''
* It can be concluded then that: '''Night > Firepower > LoS'''
* The 'Normal' cluster is left out of the table as it has a value of 0, being neither good nor bad
Using this table, each ship can then add together the value for each stat/cluster combination it's part of to calculate the overall "Stat" rating.

|-|Special Abilities & Traits=
Individual ships can differ widely in usefulness due to special abilities or other attributes. 
These can range from extra slots to special AACIs, speed differences, Touch mechanics, special equipment, or even extra range (which can be both good or bad). 
As each of these traits is generally similarly felt across all classes, these are given flat values added to each ships' total "Bonus" rating. 
{{User:Memetails/Specialty Bonus Values}}

|-|Other Bonuses=
Additionally, each ship can be awarded bonus points based on the number of ships that exist in that particular class. 
* For example, Akashi, the only Repair Ship, receives a large number of extra points in comparison to a Destroyer, which have over 100 ships in their class.
* The bonus points are calculated as: <math> \text{Bonus Points} = \log_{NumOfShipsInClass + 1} ( TotalNumberOfShips / NumberOfShipsInClass )</math>

|-|Results=

Notes:
* '''Included:''' Modernization for HP/ASW/Luck
* Marriage
** '''Excluded:''' Stat gains for LoS/ASW/Eva
** '''Excluded:''' Reduced consumption of Fuel/Ammo
** '''Included:''' Extra HP & Luck
