A few milliseconds of additional bloat added to the 90msec from my house to Fremont is easy to ignore. Tacking a few milliseconds onto 16msec from Cloudflare's DNS shows a significant delta - and worth reporting.

Hmm, that is not easily doable as it is now, unfortunately...
One way to achieve something like it is to add another test parameter
that would override the ping destination of the existing tests. I.e.,
instead of adding a new ping host, you'd just get the ability to
override the one(s) already defined by the test...
Would that work for you?
