  What I said was "are you sure that shadow tests are always done with a
fading light regardless of distance". Or in other words, "are you sure
POV-Ray doesn't have a check that if a fading light source is far enough,
it doesn't skip doing shadow tests".

  I don't really understand how you misunderstood what I said.

  With a simple mathematical formula. From the light source parameters
you can calculate what is the distance at which the effect of the light
source drops below negligible.
