Hmm.

If I’m reading those fping commands right, you’re sending a total of 36KB/s in ICMP (4x 60pps 150B), which should fit into the 25% Voice allocation on a 2Mbps (250KB/s) uplink.  Under these circumstances, Voice should still be prioritised relative to Best Effort.  Adding over 10ms of RTT is not what’s expected.

Let me think carefully about how this filters through the priority layer.  I may need to tweak it a bit.
