Ping statistics for xx.xx.xx.xx: Packets: Sent = 120, Received = 99, Lost = 21 (17% loss), Approximate round trip times in milli-seconds: Minimum = 550ms, Maximum = 691ms, Average = 468ms So, the average time for those packets is significantly less than the minimum time, eh? They've clearly divided the total time for successful replies by the number of total packets *sent*, not *received*. Smart, huh? It certainly looks like that Windows ping command is much more efficient than the competition! Greg.
