I'm having trouble understanding the formula for how much time something takes to mfg in eve. I know about the fuzzworks site but I would love to be able to make and use my own software (mostly spreadsheets). I'm reinventing the wheel to better understand it! Fuzzworks is great, though, and I still use it.




My understanding is that it takes:

Base * BPO Mod (i.e. 80%) * Facility (e.g. 1 or 0.75) * "skillModifier"

For the skill modifiers you just multiply them all together, for maybe like 0.8 * 0.85 (ind/adv ind) and then same for implants if you have them (0.99?)

That should result in an accurate time, right?


I just read through this link and other than ignoring the part about teams I think I understand this. https://eve-industry.org/export/IndustryFormulas.pdf the part that's the skill modifier with the funny Greek symbol formula (similar to a sigma in placement but obviously means something different).

Thanks very much for your help! Please let me know if I'm off here.

I can't answer your question, but this might provide some insight if you study it a bit.

Hopefully Steve or someone else will be along shortly...

Sigma = Add
PI = Multiply

In EVE, nearly every bonus is applied via multiplication:

Base * (1 + bonus1) * (1 + bonus2) * (1 - bonus 3) ...

The base time *(1-(blueprint te/100)) * (1-((industry skill *4)/100)) * (1-((advanced industry skill*3)/100)) * Facility modifier * runs;

Woo! CSM XI!
