If i put 50 wood in any furnace, and any raw food in there as well, the result is 50 wood used and only 17 food cooked.
Here's my json (no code errors this time, as i re-wrote it from scratch last night)

wood use ticks a little faster than 1:1 on metals
wood use ticks a lot faster than 1:1 on food

A> can i make things smelt quicker to match the wood use?
B> if not, can i slow the wood use down to match the cook / smelt amount?

Please advise - I've been going mad with this mod for a few days (and several posts on here)
I would also like to say thank you for updating it, to the latest version and fixing the burning / and other issues. It's very much appreciated.
