What I find interesting is my results are different than everyone else.
Of course Xfinity/Comcast certainly has better peering with Netflix than the average WISP. Or the SpeedTest server I’m connecting to sucks. I’ll just blame my Mikrotik router.

They probably work better when there is a physical limit like DSL line rate. Speed tiers can be problematic, since there is often at least some burst above the subscribed rate. I see this particularly on the speedtest.net upstream graph, which will jump up to a high number and then gradually drop the test rate until it finds the sustained rate, but customers interpret the graph to mean the “speed” is not consistent. Speed tests also don’t account for typical use which is lots of different content sharing the connection. Just because your 100M connection doesn’t pull 100M from the speedtest.net server doesn’t necessarily mean you can’t achieve 100M of typical mixed traffic. At least this new test is clear about what it is testing: how much traffic can you pull from Netflix. And given how Netflix dominates Internet traffic, that’s not an unrealistic thing to test.
