Hi everyone,

I'm the author of Production Rates Calculator Extreme, the most advanced rate calculator currently available on the mod portal (biased opinion). If you're one of the "no one needs ratios, just build more" guys you can stop reading here, but in case you want to have an efficient factory without going into complicated planning tools, this mod might be for you. Or you might already be using it - it's already out for a few months and even made it into Soul-Burn's mod recommendation list.

The mod supported ghosts basically from the beginning, but there was always one important piece missing: Furnaces didn't have their recipes assigned. This has changed, the mod now analyzes the flow of items and fluids - for very clean results from ghosted blueprints. Yes, even furnaces and recyclers. Yes, even when fed multiple items into a single building, as is usually done in quality upcycling loops.

Here are a few screenshots as a teaser. For more information see the mod page, I've also written a short manual which you can find there.

The whole item/fluid tracing feature is very new and has lots of code so I still consider this feature experimental. To improve it even further I need your help: If you find any edge cases that aren't covered yet (or other bugs or feature requests), please create an issue on the github page and I'll try to address that. I'm quite committed to that project and want to give it the amount of polish it deserves.

Those furnaces produce copper plates, because of those mining drills on a copper patch.

The quality upcycling loop from FFF #375. Normal and uncommon circuits are cycled back into the recyclers.
