Lima, OH Spectrum/Charter Severe Node/Hop Latency Issues

ICMP response time from a router/device is not a great way to judge if
there is an issue or not.  The devices generally have control plane
policing and responding to ICMP is not prioritized at all.

I would suggest your engineer setup something on their end of the
connection that you can ping, and start there.

Leverage something like smoke ping to something on their LAN, or even the
public IP on their RG/Modem.
