When add "crushed coal tech" is enabled, and also https://mods.factorio.com/mod/alloy-smelting is active. I think that also the coke from crushed coal recipe should move to this new crushed coal tech, now that recipe remains at the oil tech.

Also on similar note, perhaps coal should have slightly higher energy now the recommended yield from crushed coal is 25%
coal = 4 MJ
crushed coal = 3.2 MJ

bonus is 25% --> 3.2 * 1.25 = 4 MJ
So the real gain is the 5% chance of a return of coal?

Your suggestions have now been implemented in version 1.12.0.

This mod exists because I think the 50% extra yield bonus is far too powerful so early in the game. That’s why I like the adjustment to lower the fuel value to compensate for the extra yield.
I’ve decided to add a new mod setting so everyone can choose whether the fuel value should be 3.2 MJ or 4 MJ (as in vanilla). The idea is that, just like in real life, the fuel value doesn’t increase or decrease when the surface area is expanded by crushing.
However, this option is disabled by default.
I hope that’s okay for you.
Thanks for your suggestions!
