I tested the factory outpost with just 6 pawns and noticed that the factory outpost's resource output is all over the place. The plasteel forge option produces about 2,100 plasteel per quadrum while the steel excavator produces about 1,000 steel per quadrum. The option for the outpost to produce fish is also unusually massive, it's possible to produce over 10k fish per quadrum from 6 pawns per quadrum.

The option to change the output of the factory outpost doesn't work except for time per delivery and time to pack up the outpost.

I examined the code of the mod in hopes of changing the factory outpost production but I'm unable to find any integers that impact how much the factory outpost produces:

<description>Places a temporary, autonomously-led factory that specializes in production and fabrication of goods using machines based on mechanoid technology. As with the machines normally, a wide variety of goods can be produced. Once an ample amount is produced, a delivery will be made at the outskirts of a faction's primary colony.</description>

Does anyone know where should I look so I could change the factory outpost's production?
