Configuring charcoal output?

This is the current config for my server, and it seems to be working fine but I am wanting to have a certain charcoal ratio for the players. Is there any way I can change the chance of it to be 100% so for every wood there is charcoal coming out, or is there is some weird tweaking I need to do with the plugin. Meant to be half the smelting time, while still using the same stuff.
"Output Multipliers": {
"global": {
"global": 1.0
},
"furnace": {
"charcoal": 3.0
}
},

I am having the same issue, I have been changing my charcoal output but nothing changes either. 2k wood smelts roughly 1.5k charcoal, and it is not static its anywhere from 1400 to 1600.

I changed output from 1x to 1.3x and nothing changed ...?

Maybe someone with further knowledge could help us both out?
