[Bloat] goresponsiveness learned a few tricks...

[David Schinazi]

My understanding is that Apple chose to report RTT as an inverse because
people are used to "higher number means better". The target audience for
network speed tests is the average slightly-tech-savvy consumer, and those
aren't all familiar with what latency means. Also, car enthusiasts like
RPMs :-)
