+In ping-mode, the display is a logarithmic scale, calibrated so that the
+three rings represent ping times of approximately 2.5, 70 and 2,000
+milliseconds respectively.  
+
+This means that if any the hosts you are pinging take longer than 2
+seconds to respond, they won't show up; and if you are pinging several
+hosts with very fast response times, they will all appear close to the
+center of the screen (making their names hard to read.)
