I'm not so sure that's valid. I mean the variability  under 10K  
transactions (total) is so large that I think we have to assume that  
we lose the precision in the range...
PS: it took me a minute longer than expected to disable the AFW,  
therefore the ~72K and ~97K points that are green and clearly in the w  
AFW range are really with the firewall enabled.


Here's the plots with a moving average. Initial average is inital  
point, so it's an approximation (from awk:
awk 'BEGIN { sum=0;} {if (sum==0) sum=$4; sum=(9*sum+$4)/10 ; print  
$0" "sum;}' sorted.dat  > ma.dat
)
