Mining Laser Upgrades and Miners. How Does the Bonus Stack?

Hello, just curious how mining laser upgrades and mining skills apply to each turret.

For example, a Retriever fits two strip miners and the retriever gives a 25% bonus to strip miners. This seems to make sense, giving each miner 125% mining yield for a total of 250% yield.

The Procurer then gives a 150% bonus to strip miners for a a total of 250% yield, same as the Retriever.

What I'm unsure of, is how to the upgrades apply? As another example, does each strip miner benefit from the mining skill (25%) individually on the Retriever for 150% per miner for a total of 300%? (which would exceed the Procurer by 25% given the same boost) Or is it somehow multiplicative?

Thanks to anyone who has the answer to this, it has been bugging me a bit. And I know you can fit an additional Mining Laser Upgrade on a Retriever than on a Procurer, but I'm more interested on how the boosts apply.

All mining barges have effectively 3 strips.

Procurer: (1 + 200%) * 1 = 3
Retriever: (1 + 50%) * 2 = 3
Covetor: = 3

Everything multiplies.

Ahh I see what I had wrong. Thank you. So Covetor would be the best to apply bonuses to, and Procurer would be the worst. I had thought it was the case, but I wasn't sure. Thank you.

Ye they shuffled the bargebonuses again a bit, but instead of thinking how one module changes the ships, think how the ships themselves are different. Covetor with 3 strips, others with 2.5.

Covetor is rather useless solomining, tiny orebay, but does mine more than the others.
Retriever is nice solovessel with large orebay.
And procurer is practically gank immune if you are worried about that.
Procurer isnt that far behind retriever (1 lowslot) in mining power but you do need twice the trips to empty the orebay.

One mining upgrade helps procurer and retriever just as much.

Mathematically, it does not matter how you apply the bonus, either per miner or on the sum. The result is the same, as long as you do the math right.
Same goes for the upgrades, doesn't matter if you factor them in per miner or on the sum, still the same result. Don't forget that mining upgrades have a stacking penalty afaik.

You're wrong on the multipliers. Things have changed.

Procurer gets a 150% bonus for yield.
Retriever gets a 25% bonus for yield.

So they're sitting at 2.5 strips each, while the Covetor gets 3.


The retriever can fit 3 MLUs, to a Covetor's 2, but the 9% bonus isn't enough to tip things in it's favour. It does mean it can beat the Procurer.


The Covetor also gets a 4% reduction in duration, per level, compared to the Retriever/Procurer's 2%.

So, max skilled, badly fit (i.e., for max yield):

Procurer: (2.5 * 1.09 * 1.09 )/ 0.9 = 3.3 Strip miners worth, per unadjusted cycle.
Retriever: (2.5 * 1.09 *1.09 * 1.09) / 0.9 = 3.6 Strip miners worth.
Covetor : (3 * 1.09 * 1.09) /0.8 = 4.5 strip miners work.

The Covetor pulls in 25% more ore than a Retriever.

The downside is that it has a far smaller bay, at 7,000 m3 to a Retrievers 27,500 m3 bay (max skill) But if you have mining support (An Orca is great here, with bonuses. But you could use a Deep space transport, or a Miasmos. Or just Jetcan (bad idea) ) then a Covetor has the edge.


You should also note that if you're getting a cycle time reduction from an orca, or just the yield boost from Mining Foreman, that 25%, while remaining 25% better, is more ore in absolute terms.

Woo! CSM XI!
