How was this calculated? That's an unusually high ratio of up to down, so
my suspicion is that they aren't time correlated; they're also not /normal/
or /evening/ peaks, I'm expecting.

There's a big difference between individual peaks of upload and aggregate
peaks of upload; most people aren't streaming high symmetric bandwidth
simultaneously. Consequently a peak busy hour online load, I'm finding, is
still much more like 8:1 over all users (idle and active), in Preseem's
data set.

In addition to speed tests being, like democracy, the worst form of
government except for all the others that have been tried, it would be
instructive both for end users and ISPs to choose, agree on and understand
specific percentiles of expected performance at idle and at peak busy hour.

Has anyone solved the math problem of distinguishing (from outside) a
constraint in supply from a reduction in demand?
