And repeat:
What I stumbled upon was the word efficiency. It was mixed up with productivity. That happens often...
And there is another word, which is not so good: effectivity.
Now one point when I added it to the wiki (https://forums.factorio.com/wiki/inde ... tle=Module): it is in my opinion "efficiency" not "effectivity".

http://en.wikipedia.org/wiki/Effectiveness

And this (lol): http://de.urbandictionary.com/define.ph ... ffectivity
And as said some month before: in German productivity means something very different and efficiency is better described as effectivity, because there are different types of efficiency.

http://de.wikipedia.org/wiki/Effektivit%C3%A4t
http://de.wikipedia.org/wiki/Effizienz
For English speakers this might sound not very important, but indeed it is a problem., cause I'm nearly sure, this is also for other languages the case.
My suggestion is to change the glossary here. But I've no idea how.
