We have tried to be more dynamic than that. If it turned out that something was too out of line, then we looked for a different way to calculate things, or changed the shape of the curve.
All of this was enabled by Tom's latest dynamic map, and the region borders we drew. This let us calculate things like population density, length of coastline, percentage of coastline, and other such interesting things. The only arbitrary thing defined for a region is the max population. All the rest is procedurally derived from the actual properties of the region. It's pretty cool.
