I think you are correct with the interpretation.
Your and others' certification that the BT10 main router + satellite AiMesh is working very well, as supported by your data, is encouraging me to go get my 2nd BT10 unit as a satellite - to make full use of the 6 GHz band. Even as of now, I'm getting about 2 Gbps Tx Rates while using my AX58 as AiMesh satellite of the BT10, on the 5 GHz band, when the 6 GHz range gets far from the BT10!
This is hard data that should be immune to FUD.
Good to see the 16 ms latency as well, as that is as good as it gets with Xfinity, for their typical home service (implying that the BT10 mesh through the satellite is not introducing much latency overhead)
