Well, when I checked it from my home computer it whent in intervals. Going something like this :
0, 24 , 68, 69, 89, 120, 169, 200 and so on up to 400+ , then it slowly whent back towards 0 again, and same thing over and over. The numbers are not important, just that it goes in waves, low-high-low, and it seems random scripted. That, or he makes 1 guest appear as 50 or 100 on his forum
