Seems to vary a bit more with the new region pattern. This was good before because the average over chunks was more broad, but now it's likely to catch a lot of the same biomes for a while is my guess. Might want to look at bumping the sampling interval.

I don't feel too strongly about this anymore; it is somewhat good to note that generation varies quite a bit depending on terrain, and I also want to avoid bumping the interval too much and making it less obvious when the server is lagging or having other issues during generation.

For those who are interested, a system property has been added in cadf998 to control the interval.

To use it, add -Dchunky.sampleInterval=X to your startup flags, X being the number of seconds to sample. The minimum sample interval remains 10 seconds. Sub sample interval shouldn't matter too much, but for performance reasons it is automatically configured to be a fifth of the sample interval.
