Still not 100% sure how it works, but I should at leat have the tools to figure it out when I'm less sleep deprived.
Thank you both for the help.

Quick check assuming left side is correct:
319÷25 = 12.76 crafts per second
12.76*(90 + 65*0.75) = 1770.45.
65 is amount of heavy oil given by bonus cycles as they do not give catalyst.


Yea I didn't know about catalyst restrictions.
But Would you mind explaining the math you're doing here? I ...

The game doesn't do that. The input and output are handled separately.


Here is the wiki part where it's explained :

Some recipes consume some of the same items or fluids as they generate. These items are "catalysts" in that recipe. In those cases, productivity bonuses usually do not apply ...

[Heavy Oil per Craft] / [Time per Craft] * {Machine Speed] * {Productivity]
90 / 5 * 0.7 * 1.18 = 14.868/s


This seem incorrect calculation to me, in that i think there is an additionnal thing to consider , productivity doesn't apply to all the heavy oil per craft, some of it being used as ...

I was making a coal liquefaction build using manual math for exact numbers when I noticed that the heavy oil/s in the Recipe crafting throughput tooltip (RCTT) was incorrect.
After toying around for a bit I realized that this only happens when the refinery has productivity.
Every other number in the ...

This isn’t a feature I use often, but a couple days ago I was placing down some belts that fed chests for loading a train and I went “Man I need to place a lot of belts that are facing perpendicular to the direction I’m placing them…. Hey wait a minute, there’s a bind for doing that quickly ...

Another thing I found to add to this report.

Create an underground belt ghost that goes under something.
Attempt to drag-place the belt & tunnel.
The exit of the underground belt fails to place.
I've tried under a number of things, this seems to fail every time.
The expected behavior is the exit ...
