I think we are WAY overanalyzing... The only tool a typical end user has for testing is ping and tracert on their windows machine. They do not care about packet processing, icmp priority, processor speeds, forwarding paths, mpls, internal bus, they only care about what the ms latency is between each of their trace route hops. They do not care if it is accurate or is even relevant. When they call into support they only care that their buddy down the road gets 45ms to yahoo.com with BST and gets 82ms with Centurytel. I have always noticed that about this list which is why I rarely post. Seems that people spend more time picking apart your question then actually answering it. I am not asking which tools are best or most accurate. I am not asking if ms latency is an accurate measure of DSL service. I am not asking about DSLAM configurations. I am simply asking what a typical and acceptable traceroute/ms latency is for a home DSL account. I have received several very good answers that have answered my questions perfectly. Thank you to all that answered. I have enough information to accomplish my end goal now, again thanks for the help.

No, it's not, because routers generate ICMP TTL Exceeded packets with totally different machinery, separated from the forwarding path. Many factors influence the ms numbers traceroute reports (MPLS, main CPU load, priority on internal busses), and only some of them correlate with forwarding latency.
