right ive got 2 lots of stats here from a traffic broker. one is logged with porngraph for which i always use and one is there internal stats.
now compare and tell me if porngraph counter is out of not logging some countries or am i being tricked?
here are the pages
porngraph stats
 
broker stats
 
the traffic was being sent to a console which i now nuked the images.
the server is showing raw stats but i use porngraph all the time with many different traffic brokers and methods and they have all been spot on.
