Note that you don't need RCP round an FP. Just a tight cluster of cities as close or closer to the FP than the nearest city is to the palace, so it's a disk not a ring. Rings are only relevant round the palace.
[edit] By the time we get 8 + 12 cities in two rings we'll be building 100% corrupt cities. We don't need 8+16 in the rings. We prolly can't get 20 in two rings, but we should be able to close to the OCN.
