Hello, I've recently started using this mod and came across a few issues. First, in the description of parts that recycle resources, it says something like "efficiency multiplier 5". I only found out what it means after some searching. Could you change the description into something more understandable ? For example, "80% efficiency" or "recycles <input> into 80% <output> and 20% waste". Since you can calculate one from the other, it makes sense to list the more comprehensible number, which is efficiency I think. Also, when I was looking up the meaning of that efficiency multiplier, I found your spreadsheet. It is very well researched, but I found some inconsistencies with the recyclers (starting at row 312 in the spreadsheet). I'll go through them in order : Water splitter - is fine. Carbon extractor (CO2->O2) - this took me a while. I didn't know where its efficiency came from. It is 100% efficient in the sense that it converts 1 mole of CO2 into 1 mole of O2. Its inefficiency comes from Kerbals, whose breathing converts 1 mole of O2 into 0.869 moles of CO2, thus making the overall oxygen cycle 86.9% efficient. Could you maybe add this to the wiki ? Sabatier recycler - it doesn't make sense to speak of its efficiency, because it's not a closed cycle like the previous one. This one uses water in each cycle, so it's like the combination of water splitter and carbon extractor. Water purifier - I think there is a miscalculation in the spreadsheet, which comes from cell C362. It says : C362=C360*(D210/D213)*J360, but I think it should be C362=C360*(C210/C213)*J360. Currently, there is actually more water produced than spent. (it's something like 100 water >>>Kerbals>>> 120 waste water >>>recycling>>> 110 water)
