Accuracy & Evasion

*"To hit **and** not to be hit, that is the question." - unknown Nova Scholar*

## Accuracy

Base Accuracy depends on the weapon.

* Kinetics have low accuracy
* Missiles have medium accuracy
* Beams have high accuracy

Additionally, within each weapon category: the slower a weapon fires, the more accurate it is, but at the cost of lower damage.

Higher rarity weapons are more accurate.

## Evasion

Base evasion depends on the Engine equipped on the ship

Higher rarity engines have more base evasion.

Larger size engines have more base evasion (for no reason at all)

## Ingame Formula

The following formula can be found on in-game, on the Dock screen.

This means that the Base Hit Chance is 30%. Higher accuracy increases this value, while higher evasion decreases it. Generally speaking, about every +1000 accuracy means +10% hit chance.

### Example

Weapon accuracy (including bonuses) 7500, target evasion 4000

Hit chance = 30% + (7500-4000)/10000 = 30% + 0,35 *(this means 35%)* = 65%

### Exception

Ship skills that do not use equipped weapons have always 100% hit chance. These are attack charge (Argo) / conversion attack type skills (Mycanea)

## Hit rate affects your DPS

Because the hit rate is not that terribly high, your wepons will often miss. If they do, they will do 0 damage in that round. Therefore: **DPS \* Hit rate = true DPS.**

Increasing accuracy increases your true dps. Increasing evasion reduces your enemies' true dps.

### Example

A ship with 100k dps but only 6k accuracy, against a relatively agile target with 6k evasion will only hit 30% of the time. 3 shots will land out of 10 (30% hit rate), resulting in a true dps of 30k.

Increase the accuracy to 8k and the dps increases to 50k (50% hit rate).

## Understanding Accuracy And Evasion When it Come to Your Damage/DPS

### Accuracy and you

Accuracy is a fundamental and important part of the game, and will go a long way in helping you be a better fleet builder, and thus a more effective commander.

Lets dive right in.

As previously mentioned, the base hitrate for all weapons is 30%. This baseline is done by an equation that starts at 0acc and 0eva.

This scales linearly, if the weapon has 3000acc and its shooting at a target with 3000eva, then the hitrate is 30%. If it is 8000acc and 8000eva, it is still 30% hitrate.

Simple rules.

If your accuracy is 1000 less than target evasion, your hitrate is reduced by 5% (NOT 10%) to 25% hitrate. Example: 3000acc weapon against 4000eva = 25% hitrate.

As previously mentioned, **every +1000acc over enemy evade (at any scale), = +10% more hitrate.**

998000acc against 997000eva is still only +10% hitrate(to the base 30%), and thus 40% hitrate. (These are exaggerated numbers).

### Hitrate and you

Hitrate is what it sounds like. Of the number of times a shot is fired, there is a chance the shot will miss **and do no damage.**

If you shoot 10 times, but only hit 3 times, you deal the damage of 3 times. If each shot does '1' damage, you deal 3 damage out of 10 shots.

Which is 30% of your listed damage.

--Follow the math

10 hits @ 30% = 3 dmg

10 hits @ 40% = 4 dmg.

2120 @ 40% = 2120\*.4 = 848 dmg.

#### What this means for you:

Hitrate is NOT calculated for you on your DPS. Your ship DPS number doesn't factor in accuracy or evasion.

That means your DPS number can actually be A LOT LESS than what is listed IF YOU HAVE LOW ACCURACY.

### How to calculate your dps against your hitrate

**Calculate the resulting damage by converting the percentage hitrate to a multiplied decimal.**

Take 30% as the base hitrate. 30% hitrate is the same as saying 3/10 of the shots make it.

30%, is the same as 3/10. And 3/10 = .3

**.3 <-- is the number to multiply your dps by.**

1000dps \* .3(your converted hitrate of 30%) = 300 actual dps.

Examples:

if its 10% hitrate, the equation is [damage\*.1],

if it is 20% hitrate, the equation is [damage\*.2]

if its 68%, the equation is [damage\*.68]

#### --Summary

Take your average accuracy for a ship... and compare it to an evasion stat.

Every +1000 accuracy above a target evasion is +10% hitrate,

calculate your hitrate using that math by converting the resulting hitrate percentage into a decimal, and multiplying that decimal by your listed dps.

### -Damage Using Average Evasion (and you)

Average evasion is different depending on your server. Pre-post matrix, what ships have been released, the playerbase and other factors.

It can vary from 3000>5000,

What we want to establish.

1. An average evasion
2. Perhaps a tank ship evasion

Once we have that number, we can theorize theexpected damage of our weapons.

**The community average evasion is [ 4000 ] evasion.** This number is a guideline, not a rule.

#### --Calculating your dps with Acc and Eva

*Lets take a ship with 60k dps, and 8k accuracy (these are rounded)*

*subtract **YOUR ship accuracy** to **the average evasion** to find the (per 1000) difference.*

8000 - 4000 = 4000 difference, which = +40% hitrate.

*Add that hitrate to your base 30% hitrate.*

30% + 40% = 70% hitrate.

*Multiply your DPS number by your final hitrate.*

70% = .7 = (60000\*.7 = 42000), 42k dps.

42k dps is very different to 60k dps, and you could fool yourself if you arent careful.

Imagine if you had 6kacc!, you would get +2000 = +20%(+30% base) = 50% hitrate = 60k\*.5 = 30k

30k!, that is, you would be dealing **HALF** of your listed damage!

--Complete Summary

Calculating your ships effectiveness to evasion from accuracy is important to know how effective your ship, and fleet actually is.

--Bonus

Why missiles suck in this regard... -TheR

When it comes to hitchance, the more often there is a 'try' the closer the reality will be to the calculated hitrate.

As hitrate is out of 10.

for instance:

0 1 1 1 0 0 0 0 0 0

You could miss the first 'try', first volley, but then hit 3x in a row!, but then miss the remaining 6 times.

Random chance says you will hit, the hitrate number of times (3 times, 30%) out of 10....--ANYWHERE in the 10 tries.

Missiles:

Missiles have such a high cooldown..

its possible that you can only fire your weapon 4 times before your ship dies and the round is over...

and if you have a 30% hitrate...

the game could make your chance like this..

0 0 0 0 0 1 0 1 1

To even MAKE a SINGLE hit, you would have to fire 6 times!, BUT you only have time for 4 'tries' before the round is over (and your ship is dead).

**With high cooldown weapons, the actual damage dealt could be vastly different.**

So be warned, with missiles with low accuracy, you could basically miss 50% of the time, even with a hitrate of 60, 70, or 80%. You could even not hit anything at all!
