With all the changes to ships etc I'm unsure if my spreadsheet is up to date anymore.

Can someone please remind me what the equation for skills and yields are for the mining lasers/strip miners?

Thanks.

Have you ever used EVE Fitting Tool (EFT) or Python Fitting Assistant (pyfa)?

They show, and let you manipulate, the skills that affect modules.

It doesn't actually tell me what I want to know.

There's supposed to be an equation that factors in base of miner, mining skill, astrogeology, etc but I can't remember what it is.

I have a spreadsheet already but it's showing 492m3/cycle but Eve is showing 669m3/cycle in my Endurance.

This is messing with my head.

I'll show my equation based on an Endurance because that's currently what I'm flying but I can fly all mining ships other than Rorqual.

I'm using the Miner II laser which has a base of 60m3/cycle.

The following details are the bonuses of the Endurance:

Expedition Frigate: No extra yield bonuses - I have level 5 = 1 + 0% = 1
Mining Frigate: 5% per skill level - I have level 5 = 1 + 0.05 * 5 = 1.25
Role Bonus: 300% = 3

So far the boost to the mining laser is:

60 * 1 * 1.25 * 3 = 225

Mining skill: 5 = 1 + 0.05 * 5 = 1.25
Astrogeology skill: 5 = 1 + 0.05 * 5 = 1.25

225 * 1.25 * 1.25 = 351.5625

I have a level 5 Highwall: 1 + 0.05 = 1.05
I have a Michi: 1 + 0.05 = 1.05

351.5625 * 1.05 * 1.05 = 387.59765625

I have 3 Mining Laser Upgrade II: 1 + ( 3 * 0.09) = 1.27

387.59765625 * 1.27 = 492.24902344 rounded to 492m3 / cycle

I'm missing something else because without Orca boosts Eve is showing me as having 669m3 / cycle

Aha I've got a bit closer. I think I've been doing it wrong.

Expedition Frigate: 1
Mining Frigate: 1.25
Role Bonus: 3

1 + 1.25 + 3 = 5.25

Mining: 1.25
Astrogeology: : 1.25
Mining Laser Upgrade: 1.27
Highwall: 1.05
Michi: 1.05

1.25 + 1.25 + 1.27 + 1.05 + 1.05 = 5.87

60 * (5.25 + 5.87) = 667.2 rounded to 667

It's still 2m3 / cycle less but it's much closer than 492m3

Multiply it with an arbitrary 1.003 (I pulled this number out of my bunghole) and it's a perfect 669m3.

Meh. Your math is wrong *somewhere*. Let's try from scratch. (By the by, EFT also lists 669 so at least we all agree there.)

Edit: your math is wrong in that you're adding *anything*. All bonuses are multiplicative.

Miner II base yield: 60

Ship bonuses: 1.25*4
Total: 5

Skills:
Astrogeology: 1.25
Mining: 1.25
__________
Total: 1.5625

Implants:
Michi: 1.05
Highwall: 1.05
___________
Total: 1.1025

Before MLUs total: 60*5*1.5625*1.1025 = 516.796875 (so far we agree with EFT)

Now MLUs get complicated because they're stacking penalized. Skipping past the explanation for why, the bonus is going to be:

1.09 * (1+.09*.869)*(1+.09*.571) = 1.09*1.07821*1.05139 = 1.235644940971

516.796875*1.235644940971 = 638.577444103372265625 = ????

This is the wrong number, apparently.

So we try again without stacking penalties(!):

516.796875*1.09^3 =516.796875*1.295029= 669.266940234375

And we find that MLUs aren't stacking penalized anyhow(?!?). So there's your number.

Edit 2: After looking around, it seems to be widely known that MLUs aren't stacking penalized. I just made a bad assumption in there. Not sure why that would be exactly, but hey, free yield.

... and I've managed to avoid being the one to post the math.

Phew! Close one.

Seriously, if you'd done a search you'd seen how many times I've posted the math for somebody asking similar questions.

Kudos to Zhilia Mann. Tag!

Thanks heaps for that. Question though, where did the Ship Bonuses * 4 come from? The specs for the Endurance show 5% per skill level and 300% for the role bonus.

With the math above if I multiplied according to the given information it worked out bad which is why I added.

Everything I had was based purely on what I was reading from the ship description.

That's the role bonus. 300% bonus on top of the normal 100% makes 400% -- hence *4.

Aha. That makes perfect sense.

As you can tell math isn't my strong suit until someone explains the concepts which you have so perfectly done.

thanks.
