Damage per pec + decay per shot + DPS

[Zenzile]

Does anyone have equations to find these? Entropedia seems to be wrong on some things/is missing things thus I'd like to be able to find DPP + DPS + decay per shot without entropedia. Thanks!

to find decay per shot, shoot it once then use the fruit method to find it (look it up. no time / patience to explain it)

To find the decay, you can do a fruit (or stone/dung/sweat) test.
Simply put the item in the TT, then add enough fruit to bring the value up to the next pec (fruit has a value of 0.001 pec). Then go use the item once. After that, return to the TT, and do the fruit test again. The difference is the decay.


To find DPP,
Begin with the max damage
Multiply by 0.75 (average damage is between 50% to 100%)
Multiply that by 0.9 (you miss 10% of all shots on average)
To that, add 0.02 * max damage (2% of shots are critical hits)
Divide that by cost (decay + ammo)

((Max damage * 0.75 * 0.9) + (max damage * 0.02)) / (decay + ammo)


To find DPS,

((Max damage * 0.75 * 0.9) + ( max damage * 0.02)) * rate of fire / 60


Edit:
Once you find the decay for missing items, please add it to entropedia. Doing so helps us all.

Bumping this as I am trying to use this myself for weapons where entropedia misses info.
But I cant get the numbers to work. Maybe someone can see if they can figure out what I am doing wrong.

Example weapon Piron PLR-12 (L)

Fruit test to calculate decay

var 1 = Value of item before adding fruit: 14.28 ped
var 2 = Number of fruit to get to next pec of weapons value (14.29) before shot = 424
var 3 = Number of fruit to get to same pec value (14.29) after shot = 797
decay = (var 3 - var 2) * 0,0001 = 0,03730


Damage/pec

Max damage = 38
Damage/pec = ((Max damage * 0,75 * 0,9) + (Max damage * 0,02)) / (decay + (Ammo usage/100)) = 2,98509

A very happy number: 2,98509.
But Entropedia shows 2,876.

Can anyone see any obvious errors in my calculation?
Something has to be off but I just can't figure out what

p.s. I used the Weapon compare tool to find the Damage/pec

The problematic bit highlighted in red.

It's 0.373 PEC (1000 fruit = 1 PEC, 1 fruit = 0.001 PEC)

And Entropedia has 0.374 - about the same

At last working. I'm really happy for that Haruto.
Big +rep!
