   Good point. For a meaningful comparison of errors between PRNGs at a   
   specific N, the statistical variation of the  need to be measured   
   for different seed values.   
      
   I can add some code to measure this sigma at each N, with 32 seeds   
   uniformly spaced between 0 and UMAX.
