Hello again! Been enjoying the mod quite a bit. That said though, I have noticed from playing with EI a bit further (setup a full iron-ore -> crush -> leaching/solution -> recrystallization -> iron-plate -> steel-plate production line prioritizing the use of byproducts), to which I found the amount of byproducts to be a bit much for the recrystallization step specifically - that is, if the math I did was correct, it's actually sulfur positive for the amount of sulfuric acid required.

Thankfully the recrystallization byproduct probability can be configured, but unfortunately not for the sulfur byproduct. I found reducing both by a factor of 5 - 7 or so seems to have put them at a good level for the moment (50% -> 10% chance of the alternative enriched ore, and 35% -> 5% for sulfur).

Another thought, would be to either increase the sulfuric acid requirement, and/or make it a configurable setting.

As far as configurable settings, would it be possible to add settings such that the byproduct probabilities can be configured independently of each other? i.e. a setting for sulfur from iron recrystallization; a setting for copper from iron recrystallization; a setting for sulfur from copper recrystallization; and a setting for iron from copper recrystallization.

No rush on this either, as I have already created a small local mod that makes the above probability changes for the moment.

Yes, the recrystallization is sulfur positive on purpose. The washing processes produce sulfur as byproduct and I thought it would be fun to keep it that way with leeching. It also encourages players to keep the metal-byproducts to some degree in order to make sulfuric-acid on site when refining copper-ore.

I want to add more settings, like the by-product rates but I'm still thinking about how to do that. Currently tending towards what I did in Basic Chemistry with the Full Control sub-mod. Offer some settings by default and advanced settings to those who want “full control” (like myself). However, that is some rather boring and tedious work …

Glad you're still enjoying the mod and thanks for the in-depth testing, the feedback is highly appreciated!

Really really awesome mod to preface. On the same subject,

I don't think the settings are working as described:
Overwrite is enabled:
Crushed Ore: Bonus from crushing %: 0 -> +0% 1x, 100 -> 100% 2x

I did a stupid amount of testing as I was going nuts why my ratios were not 1 to 2 crushed ore with it set to 100 and it came out to about 50% bonus.
Setting to 50 came out to about 25% bonus. Rate calculator came to the same numbers as well. I think you have it set to be a multiplier on the crushing industry value of 50% instead of actually overwriting it. IF this is intentional would it be possible to set the maximum value to 200 in the settings so it can actually be 2x?
