So I've been using PingPlotter to help troubleshoot connection issues clients are having with our web application. I've had a client run PingPlotter all day and the latency is ridiculously huge. Much higher than I am sure it actually is given speedtests I've run.

Based on feedback from you fine folks here, it seems to me that I'm saturating the clients bandwidth. My question then is: Is the data I've gathered so far worthless, or can I make any assumptions based on the variations between latency during different parts of the day even though that latency numerical value is in fact much higher than it should be.

I've attached my data. Note that normal latency, based on a speedtest going to the same location that PingPlotter was, was 115 ms.
