	[SM] And rightly so... this put a nice stop to the perverse practice of selling contracts stating (up to) 100 Mbps for links that never could reach that capacity ever, now an ISP is careful in what they promise... Speedtest (especially using the official speedtest app that tries to make users pay attention to a number of important points, e.g. not over WiFi, but over an ethernet port that has a capacity above the contracted speed) seem to be good enough for that purpose. Really over here that is the law and ISP still are doing fine and we are taking low single digit thousands of complaints in a market with ~40 million households.

	[SM] But one would be wrong, at least the official speedtests over here are pretty reliable, but they seem to be competenyly managed. E.g. users need to put in the contracted speed (drop down boxes to the select ISP and contract name) and the test infrastructure will only start the test if it managed to reserver sufficient capacity of the test servers to reliably saturate the contracted rate. This is a bit of engineering and not witchcraft, really. ;)

	[SM] If you are talking about speedtests being systemicly wrong in getting usabe capacity estimates I disagree, if your point is that a sole focus on this measure is missing the way more important point od keeping latency under load limited, I fully agree. That point currently is lost on the national regulator over here as well.

	[SM] Go team!

> Ironically, the FCC testing for CAF/RDOF actually *does* take interface load into account, only tests during peak busy hours, and /then/ does a speed test. But NTIA largely ignores that for BEAD.

	[SM] I admit that I have not looked deeply into these different test methods, and will shut up about this topic until I did to avoid wasting your time.
