When smelting in both the furnaces everything is x10 but the wood isn't consumed x10 faster. Only way to get it to consume x10 more wood is by adjusting the smelting frequency hwowever then it burns the food when cooking. I have tried adjusting both "Fuel Usage Speed Multipliers" and "Fuel Usage Multipliers" but then I get smelting right and the food burns. I have tried everything. I have no idea what to try any further

Hey!
Thank you for your feedback. I will try to do something with that.

I have reverted back to a previous version I had running on my server as the config is currently a nightmare to setup and requires a lot of trial and error to try and get it working for something as simple as just increasing the overall cooking and smelting to x10 of vanilla rate. I love the idea but it is not clear what does what
