Thanks for the explanation. That all makes sense. I changed the max anisotropy to 1 as you suggested and I do see the issue. Correct me if I'm wrong, but it seems like this wouldn't really have much to do with the number of particles or layers. Rather this just seems like a normal, expected behavior when a fluid cannot support even distribution of the particles throughout its layers.
So I'm my use case, as the fluid is compressed by reducing the size of the container, I'll inevitably reach a point where the current layers can no longer support the current number of particles in them. Thus, some of the particles will be forced to the surface to create a new layer. If the number of particles in this new layer are less than the number of particles in lower layers, that's when we'll have this appearance of an uneven, 'lumpy' surface.
Moreover, the lower layers don't even have to be 'full', i.e. filled to capacity, stretching from one side of the container to the other. Since the particles are spheres, you can actually have a situation where successively less complete layers are stacked on one another in a kind of mound or pyramid type of shape. I'm guessing increasing the surface tension would largely eliminate this scenario, though leaving us with just one incomplete layer. Excluding fluid 'beading' of course.
If my assessment is correct, then wouldn't the solutions generally be:
1) Keep the scale of the particles small enough so that you won't be able to notice the uneven surface
2) If you want to use larger particles, just be aware that this is the situation and try not to focus on it
