It's going to multiplicative per skill and module, but not per level.

(1+skilllvl*0.05)*modulex*moduley

etc

Thanks, I think I understand that.

But what does the 5% per level mean in the info?

Also how does Astrogeology fit into all of this?

Thanks guys.

i know it's early and my brain is still asleep, but doing that math still doesn't match my yield... (it's 8.20am here)

Ship is a covetor

3x T1 strip miners
2x Mining upgrade II's

Mining lvl5
A/G lvl 3 (atm)
M/Barge LVL 2 (if it matters)

(char is here, if i've missed any Clicky )

my cycle produces 931M3 of ore, per 172s, per strip.

You're in a fleet with someone who has the mining leadership skill at 1.

540 * 1.25 (mining v) * 1.15 (astrogeogly iii) * 1.09 (mining laser upgrade) * 1.0783 (mining laser upgrade after stacking penalty) * 1.02 (mining leadership I) = 931

nope, because our corp is literally my bro and i, my alt and his main smash lvl 3's while this char mines and his alt salvages. he has no interest in mining and literally has lvl 1 mining just so if we do a lvl 3 with gneiss or something tasty in it, we can both go grab it.

Hence why i asked the question, because the math doesn't add up to what my miner produces.

The activation duration implies you are not giving us the correct info.

For that duration, you must have Mining Barge 1.

(1 - Mining Barge 1 * 4%) * 180 = 172.8
(1 - Mining Barge 2 * 4%) * 180 = 165.6

Re-check your in-game yield, cycle, and fit.

i thought that would have been a given, considering i'm using a covetor ?!

I also linked my character for any skills i might have missed.

I'm now using T2 strip miners and have astro geo 4 training and getting 1009M3, which still doesn't add up on the math.

i might point out, that although it might look like i'm being an ass (re-reading it, it does look that way) im actually interested to know what it is that's pushing my yield up as if there's another skill on the list i can train to get more i would like to know about it !!

That's the problem, you said you have a cycle time of 172s which implies mining barge level 1 but your skill list says you have mining barge level 2. You are not giving us the full or truthful picture. With T2 strips, your skills you linked and a coveter the new yieldis once again with mining foreman level 1. Someone in your fleet had the skill, end of story.

[quote=Aerie Evingod]Its perfectly ok not to know the answer, but calling end of story just because you don't, isn't .

refitted the T1's, just to show you a picture.

click this

Astro Geo 4 is still training, so nothing has changed since this morning.

That picture clearly shows 165.6 for Mining Barge 2, like I previously stated, not 172.

The picture also shows drones in your bay. Let me guess: mining drones.

You never mentioned mining drones. Take the drones out of your drone bay, and check the yield again.
