The API of the grinder for example supports the amount of turns it requires to process something but the recipe system does not. Suggestion: use keywords instead of modids or pairs grinder=ae2:inputitem ae2:outputitem ae2:optionaloutputitem ae2:secondoptionaloutputitem float:optionalchance float:secondoptionalchance int:energycost or grinder=ae2(intputitem, outputitem, optionaloutputitem, secondoptionaloutputitem) + float(optionalchance, secondoptionalchance) + int(energycost)
