	No, but to get full use of the method 3, you shouldn't set the same
number for min samples and max samples. The whole point of method 3 is
that it starts with min samples and adds more where they are needed.

	You might also want to take a look at MegaPov 0.7 and the
sample_spacing keyword. It causes the media to be sampled more in
parts of the render where the ray travels a longer way through the
media. In your scene, that means that more samples will get taken near
the horizon (where I assume the banding will be harder to get rid of).
