I do believe that it is something in the OS of the route server.  Unfortunately in the Cisco IOS, I can not adjust the rate, however I found that it always drops the 200'th packet.  If I do multiple individual pings back to back (with one second or more inbetween them) that repeat 199 times, then there is never any loss.  It also explains why I can do the same test to other devices across my MICE connection, and do not drop every 200th packet.  Also by being specific to the 200'th packet in a row that tells me that there is not a speed/duplex mismatch, or a cable issue as I had originally worried about (since they would be random, or on a specific time interval, not based on a exact packet number).

I've seen that when flood-pinging BSD boxes (but not Linux).
If you can throttle the rate down (-i 0.1), rather than flood pinging, then the artifact may go away.
