I don't think you can measure backbone loss using ping unless you control both ends and ensure that both last-miles are not contributing to the problem.
I think there are several different areas to investigate. The main one is whether your packet gets handed off between two "backbone" IPSs that are currently squabbling about who is going to pay whom how much. The obvious example is Netflix vs Comcast.
I don't have any numbers, but I think over the past 5 or 10 years, all the major ISPs have set things up so that all their internal links are overprovisioned. You might notice packet loss when a link goes down and the traffic patterns get rearranged. (I know you can see changes in transit time using NTP.)
I have an old/slow DLS link. I get close to 0% packet loss if my last mile is not busy and lots of loss when it is overloaded.
