It is highly unlikely you'll ever have to correct anything that scores 
0.009 or 0.991 (ie, thresh_update = 0.01).  In the very unlikely event 
that you did, I can't imagine errantly running -N or -S would damage 
your worldlist.  Remember that it's all statistical in the first place, 
so adding a miniscule amount of noise in this way will not hurt you.  It 
would only start causing problems if you set a very high thresh_update 
value, which would defeat the purpose in using it in the first place.
