Should match real world, that is what most validation studies tell. 
Still, how do you interpret the pixel values, and how did you define 
material and light sources? Are you sure you did not get confused with 
units somewhere? It is hard to debug a scene we do not know, maybe you 
could describe the setup or even put a sketch to some public ftp or website?

Good luck, and I always thought that man mad(1) should be a redirect to 
man rpic(1) ;-) CU Lars.
