Petroleum Coke Dust weight / electrolyzer recipe

I was browsing through NEI today and I noticed something strange about Petroleum Coke.

Petroleum Coke has a chemical formula of C2S. Assuming it follows the usual pattern you see in GregTech, that should mean that 3 units of Petroleum Coke contain 2 units of Carbon and 1 unit of Sulfur.

As expected, there’s an electrolyzer recipe that allows you to separate Petroleum Coke into 2x Carbon Dust and 1x Sulfur Dust, however it only takes 1x of Petroleum Coke Dust, not 3x as expected. Is this an oversight?

Another thing I noticed is that 3 units of Petroleum Coke is somehow lighter than the 2 units of Carbon and 1 unit of Sulfur it’s made up of. Here’s my math:

1 unit of Petroleum Coke is 103 + 2/9 = 103.222… kg.
3 units of Petroleum Coke is 309 + 2/3 = 309.666… kg.

1 unit of Carbon is 251 + 8/9 = 251.888… kg.
2 units of Carbon is 503 + 7/9 = 503.777… kg.
1 unit of Sulfur is 229 + 2/3 = 229.666… kg.

2 units of Carbon + 1 unit of Sulfur = 733+4/9 = 733.444… kg.

If 3 units of Petroleum Coke = 2 units of Carbon + 1 unit of Sulfur,
then 1 unit of Petroleum Coke should equal (733+4/9)kg / 3 = (244 + 13/27)kg = 244.481481… kg, not 103.222… kg like it currently is, shouldn’t it?

Yeah this is a complicated thing, it is intended to be 1 → 3 in the Recipe, I can set the divider manually and do so for a lot of Materials actually.

In case of coal I had to set some weight parameters manually to keep some semblance of consistency in one way, while sacrificing it in the way you described too.
