Take your time, I'm just thrilled to see this working so well so far.

are the best measure of "feel" I've found, so far.

I've experienced the same when our network switched from LibreQoS using
fq_codel to LibreQoS using CAKE. Really hard to quantify it but the
"snappiness" or "feel" is noticeable to end-users.

Thanks to monitoring things beyond our control, some of the outliers tend
to be *really bad* - even if the network is fine. There's literally nothing
we can do about a customer trying to work with a malfunctioning system
somewhere (in space, for all I know!)

True. And it can be sort of helpful for troubleshooting WiFi latency issues
and bottlenecks inside the home and such.

Perhaps we can use ePPing just for this aspect? Or instead we could use
cpumap-pping but with all HTB classes set to high rates (no plan
enforcement) and no CAKE leafs.

Good idea. I've now added both a standard (preseem like) table and
"metaverse-ready" table of Node (AP) TCP Latency on the InfluxDB template.
