Packet loss to the 10.x hop is most certainly worth considering - on all CMTS apart from the BSR whose first hop is a public address that is the CMTS.
Seph - a traceroute is simply a ping repeated with incrementing TTL until destination reached. The Cisco kit answers from the 10.x address which the cable modems talk to so that is what is seen. Either way it's the first hop after the HFC network and should be considered within diagnostics.
The cable modem does not show on any traceroute, it bridges all packets apart from those directed to its' management address so doesn't decrement TTL and doesn't appear in traceroutes. One can ping the cable modem's 10.x address if you happen to know it, it will happily respond, but it's a pointless exercise.
