# Relationship between sea stats and points

The aim of this research is to find the relationship between sea stats and sea battle points on Ocean Overlord list.

## Methodology

Points on Ocean Overlord list are updated every time player logs into the game. They are calculated using players stats during the login. Loging in without sea gear on will of course drastically reduce players points on the list. We can use that fact to figure out the relationship between stats and points. For example, we can login, write our points down, unequip one of the jewels with sea stat from sea general, relog and write our points again. Subtracting those two values we wrote down, we can figure out how much points we lost. We can then take that value and divide it with the amount of sea stats we took off our general and we will get how much points that particular stat gives us. Similarly, we can test all other stats. It is important to note that the game takes maximum amount of Hull Durability, Sail Durability, Sailor Amount and Cannon Amount. Additionally, some stats are decimal numbers even though they are shown as whole numbers. The game will use decimal numbers to calculate the score. So its important to use the decimal number which can be gotten by hovering mouse over the specified stat until tooltip pops up.

Structure level 100 points
Hull durability 0.1 point
Sail durability 0.1 point
Sailor amount 10 points
Square sail power 60 points
Fore-and-aft sail power 100 points
Oar power 200 points
Turning speed 400 points
Cannon amount 50 points
Ramming Force 100 points
Cannon hit rate 200 points
Ship dodge rate 200 points
Cannon attacking 200 points
Cannon defense 0 points
Sailor damage 0 points
Sailor defense 0 points
Ramming damage decreased 0 points

## Breakthroughs

Trough the research, we had several breakthroughs which brought us one step closer to the final formula

### Only maximum stat values are used

The first breakthrough came from the realization that sea uses maximum stat values during points calculation, unlike land which uses current values. This means that regardless if a player relogs with half Hull Durability or full Hull Durability, his points will not change. The game will always calculate the points as if player had full Hull Durability. Same thing applies for Sail Durability, Sailor Amount and Cannon Amount. This can easily be verified in game by reloging once with full sailors and then dismissing most of them and reloging the second time. Between the relogs, points on ocean overlord list should stay the same.

### Turning speed from Honored Officer rank doesn’t give points

The second breakthrough came from the realization that any turning speed added trough the Honored Officer rank system add towards your total stats, but will not add any extra points. This can easily be verified by reloging and checking points, then adding +1 Turning Speed trough the rank interface, then reloging and checking points again. The points on ocean overlord list should stay the same, which proves the +1 Turning Speed didn’t add any extra points.

### Some stats are decimal numbers

The third breakthrough came from the realization that some stats are decimal numbers even though they are shown as whole numbers. Specifically, Square Sail Power, Fore-and-aft Sail Power, Oar Power and Turning Speed. Hovering over those stats in game, a small tooltip pops out, showing the value as a decimal number. In order to do an accurate calculation, they need to be used.

### Cannon amount is always shown as an even number, but it can be an odd number

The fourth breakthrough came from the realization that Cannon Amount is shown as an even number on the stats list, but can be an odd number. Trough ship retrofitting, its possible to get an Inboard Gun Platform with odd number of cannons. In case the player has odd number of cannons, Cannon Amount will round down to the nearest even number. Additionally, player will never be able to use that one cannon. Cannon Amount will be shown as an even number in stats list, but the game will actually use the full number during ocean overlords points calculation.

## Formula

\begin{align*} Points\ =\ \lfloor\ &Ship\ Level\ \cdot\ 2000\ -\ 200\ +\\ &Maneuverability\ Level \cdot 100\ +\\ &Military\ Level \cdot 100\ +\\ &Structure\ Level \cdot 100\ +\\ &Hull\ Durability \cdot 0.1\ +\\ &Sail\ Durability \cdot 0.1\ +\\ &Sailor\ Amount \cdot 10\ +\\ &Loading\ Capacity \cdot 2\ +\\ &Square\ Sail\ Power \cdot 60\ +\\ &Fore\ and\ aft\ Sail\ Power \cdot 100\ +\\ &Oar\ Power \cdot 200\ +\\ &Turning\ Speed \cdot 400\ +\\ &Cannon\ Amount \cdot 50\ +\\ &Cannon\ Hit\ Rate \cdot 200\ +\\ &Ship\ Dodge\ Rate \cdot 200\ +\\ &Cannon\ Attack\ Rating \cdot 200\ \rfloor \end{align*}

## Problems

There are still some unresolved problems. Some calculations are off by 1 to 2 points. We noticed this happening to characters with odd amount of cannons. There could be a connection between. Additionally, its possible there’s a rounding error somewhere in the formula.
