Does GURPS Space consider Earth to be an Affinity 10 planet? It's obvious it's Habitability 8, but in order to have a sufficient carrying capacity to account for the world's population (10 B) it would have to have Very Abundant resources to get to Affinity 10.

Or am I missing something in the Carrying Capacity calculation?

Base Carrying Capacity, TL8: 10 M
Affinity Modifier, Affinity 10: 1000
Affinity Modifier, Affinity 9: 500
Diameter: 1

10 M * 1000 * 1^2 = 10 B (Enough!)
10 M * 500 * 1^2 = 5 B (2.5 B short!)

If that's the case, I need to reconsider my "Average" resource planet. I modeled its mining activity based on Earth, tweaked for lower tectonics and volcanic activity. But if Earth is Very Abundant, that Average planet would be far less rich in minerals than I've envisioned.
