Finland is showing too many place names. Helsinki is crowded out from rendering at most zoom levels.

At z5 we should only have 3-6 place names per country.

Figure out a measurement of average on ground size of a place name label, set up the generalization such that at most X% of the country size is covered (not by actually measuring this when doing generalization, but just by estimates when designing which labels to include). I don't know what X should be, figure out a decent measure or give me options to try (I'm assuming that place name generalization cascade should be pretty fast).
