Something else which I just discovered by chance. Scaling the container 
in which the media is put to the original object's bounding box, reduces 
dramatically the number of samples needed. Initially, I used a standard 
box{-1,1} and needed at least 300 to 400 samples for the skeleton. Now I 
used box{Min,Max translate Center} and only need 50 samples!
