Ack.  I did *not* know that, John.  Honestly, I only change parameters 
that affect a visual change and it's purely for aesthetic reasons. 
Increasing the ambient bounces to see the interior of a daylit space, or 
increasing the direct sampling to see the pattern of a linear 
fluorescent that's close to the ceiling, for example.  But if what you 
say is still the case, surely my tip is useless for analytical work.

Thanks for the heads up, the Robs thank you.
