POV totally skips the light.  You don't have to try to compensate.  When you
use count, POV actually tries to estimate how many photons will be
generated.  POV then adjusts the overall photon spacing to try to produce
close to the count specified.  (The final count is usually at least on the
same order of magnitude as the requested count.)
