There should be an additional mention of not using the averaged normals
approach, but using a single normal plus focal blur and antialiasing.
Clipka talks about this approach here:

The code I used is this:
texture
{
pigment { InPigment }
finish { InFinish }
normal { InNormal }
normal {bumps BlurAmount scale 0.01}
}
along with some focal blur and antialiasing.
I'm not sure how the section should be worded however.
