Thanks very much, guys. What I hadn't figured out was the number of citizens required in the "sweet spot." You both seem to indicate that it's in the 4-6 range, depending on whether I just built or am about to build a settler. I've always been impatient, and start building settlers before I grow big enough to optimize.
Sometimes it has to be 5/7 to get enough shields, especially if your bonus food tile is a flood-plain wheat, which produces none, or if you're lacking in 2-food/2-shields tiles (mined bonus grasslands, usually). 4/6 is usually better if you can manage it, since it'll take less of the lux slider to keep happy. If you have enough happy for 5/7, though, that's great due to the higher commerce you'll have.
