# What is the new ore refining formula for Athanor and Tatara citadels?

Hi, the old formula was something like this:
(Base Facility * Security Modifier * (1+ (Refining Skill level * .03)) * (1+ (Reprocessing Efficiency skill level * .02)) * (1+(Ore specific/ice processing skill level * .02)) * (1 + (Processing Implant Percentage/100)))

But new refinery citadels are giving us additional 2% and 4% bonuses to refining.
How to inject it into the formula correctly?

ANSWER: Refining Yield Modifier * (1 + (Structure Bonus/100) * Structure Security Modifier * (1+ (Refining Skill level * .03)) * (1+ (Reprocessing Efficiency skill level * .02)) * (1+(Ore specific/ice processing skill level * .02)) * (1 + (Processing Implant Percentage/100))

where Refining Yield Modifier with installed refinery service is 51%

Refer to this post!

So the base Refinery Yield is 50% as always, Structure/Rig Bonus is then added additive giving the following: BaseYield + StructureBonus + RigBonus, this will make the Base Refining yield of a Tatara: 57%, you then apply any SecurityMod/skill-based/implant bonus’ multiplicative (as you did in your post)

• Max Refining yield in Highsec using a Tatara Refinery, is: 57 * 1.15 * 1.1 * 1.1 * 1.04 = 82.48812% = 82.49% (Rounded up)
• Max Refining yield in Lowsec using a Tatara Refinery, is: 57 * 1.06 * 1.15 * 1.1 * 1.1 * 1.04 = 87.43741% = 87.44% (Rounded up)
• Max Refining yield in Null/WH space using a Tatara Refinery, is: 57 * 1.12 * 1.15 * 1.1 * 1.1 * 1.04 = 92.38669% = 92.39% (Rounded up)

Thanks for reply. Am I correct in the following:

50% base +4% hull bonus + 3% rig = 57% this is T2 nullsec Tataru
50% base +4% hull bonus + 1% rig = 55% this is T1 nullsec Tataru

This is max highsec athanor
Reprocessing Yield calc
Station % - Input 102.00%
Rig 53%
Reprocessing Skill 115%
Reprocessing efficiency skill 110%
Ore processing skill 110%
implant 104%
High/Low/Null 100.00%
78.23%

Not quite right
it is 53% * 1.15 * 1.1 * 1.1 * 1.04 * 1.04 = 79.77%

Soooooo, where is the truth guys? You’re correct in that the Tech 2 rig makes the base refining yield 53% (or in other words adds +3% to the base 50%) same with the Structure bonus, it adds +2% (for the athanor) to the 53% and that sums up to 55% before all the multiplicative(s) apply

or 57% with the Tatara

I checked a t2 rigged athanor shortly after launch and it was 78% not 79% thus its all multiplication and no addition.

I can get 72.4% yield from an unbonused Raitaru (in highsec) with Reprocessing Service module and/or in NPC stations, so if what you say is true, it hardly makes it worth it to even make Refineries with the huge price tag that goes with building them (mostly with Tatara, though).

To confirm the formula would be:

((1 + (Structure Bonus / 100)) * (Refining Yield Multiplier) * (1 + (Refining Skill Level * 0.03)) * (1 + (Reprocessing Efficiency Skill Level * 0.02)) * (1 + ( Ore/Ice Specific Processing Skill Level * 0.02)) * (1 + (Processing Implant Percentage / 100)) * Security Modifier)

I took a look at Singularity and I’ve got 76,3% for T1 Rigged Tatara in NullSec. With base chance is only 52%. What the hell? I can’t see any security modifier applied at all.

That doesn’t have a rig fitted. Security modifier only applies when a rig is installed.

``````No Rig A	73.8
HS A1		75.3
HS A2		78.2

Thanks for clarification, probably Singularity still have old data.

Hmm

With all skills at 5 I am getting 73.8 out of a high sec Tatara ?

got the implant?

A-ha.

That explains it, thank you!

maybe the refining calc has a bug on life servers

i have on the small cita t2 rig 87.5% and on the large the large with t1 only 86% seems the structure bonus is not counting

Still have some questions.

Right now I’m on NullSec Tatarawith T1 rig. It shows:
http://joxi.ru/Drlv9q5svRkLO2.jpg

So the base is 59%. Anything close to it based on security is 53% * 1,12 = 59,36%. And result would be 82.97% which is not correct.

I. 59% / 1,12 = 52,67% the value without applied SS. Base value for citadel with rig is 51%. So 51% * 1,031 = 52,67 and here it is the 1,031 coeff for 4% tataru bonus. Meeh.

Though provided table is good I’m trying to correctly reproduce formula for my calculator.

How exactly the base value is caluclated then?

The structure bonus is multiplicative not additive. Treat the rig as an override of the 50% base, then multiply everything else.

So for your T1 rigged Tatara above…

51 * 1.04 (Tatara) * 1.12 (NullSec) = 59.4048

Multiply the rest from your screenshot and you get 82.6617792 which rounds to 82.7

Refining Yield Modifier * (1 + (Structure Bonus/100) * Security

51 * 1.04 * 1.12 = 59 (Rounded Down)

Above including the skill bonuses = what you get in your screenshot
51 * 1.04 * 1.15 * 1.1 * 1.1 * 1.12 = 82.7 (Rounded Up)
