Haha, you're right I misspoke, I meant I use Factoriolab for ratios, but of course it doesn’t handle custom recipes or extra content outside the usual overhauls, so if you are using mods that change things like modules or building it won't really work

I personally like to do all the ratios in 'https://factoriolab.github.io/spa?v=11' it not only has the base game but also several versions of it and most of the overhauls
