What's the reasoning for prod rate going down? Out of curriosity.
The production would be going down as the planet gets paved over to support those 8 billion people.
I imagine resource extraction would rapidly rise until you hit 500-1500 million, then start to go back down again, in a lopsided wave shape when graphed vs population.
Notes:
(on planets with max pop close to optimum production pop)
-domed planets. The pop is concentrated in the domes, so most of the land is unspoiled.
-tiny breathable worlds. Low gravity would allow easy construction of tall buildings, so you don't waste as much surface area.
