those suffering still, install a better device... VDSL can be made
vastly more tolerable. Otherwise pretty good, and brings in

https://comcom.govt.nz/__data/assets/pdf_fil= e/0016/320326/MBNZ-Autumn-Report-28-June-2023.pdf

To pick on samknows a little bit, I think the test does not run long
enough, and should be pulling from higher than what appears to be the
75th percentile.
