First, welcome to the forum and thanks for all the data!
What games do you play? It is unlikely that your traffic is going through the same place as when you go to Cox.com. I am hoping to find you a IP that will better show the issue. As you can see, I get the same packet loss going to Cox and I am on FIOS with no issues gaming. I think it is what is called ICMP deprioritization. Notice it doesn't continue until the last hop. I am not saying you don't have an issue, just that the pingplotter data doesn't represent it well.
Also, are you playing and testing on wired or wireless? I ask because the data shows 4ms just to your Cox gateway.
At the moment, I'm trying to connect with a friends Minecraft server located in his house about 1 mile as the crow flies from mine. We're both Cox customers, so Cox.com seemed like a logical connection to test.
I also play HC Diablo 3, so as soon as there's a whiff of a lost packet, I nope the heck out of there.
I have my Win 10 PC connected to the router via ethernet.
