I have been able to get OK results with pure random shooting, but I always
had to shoot a very large number of photons. Using my jittered spiral
technique, I am able to get very good results with few photons. If
anything, it should offer better performance than a totally random method
(or even a weighted monte-carlo method).
I still don't know exactly how Jensen got the good results that he got with
his monte-carlo photon tracing.
