So if you see a 30ms hit on hop A and a 60 ms hit on hop B you can pretty much determine that hop A is 30ms away but you cant be quite sure about hop B until you see hop C's replies. To make this more interesting, its always possible that hop B or C's path to you is different than your path to hop B or C. Also, traceroute is effective at showing that the path rtt is good. Its just when you are trying to find where the latency is that things can get dicey.
