I'll make the hypothesis that there have recently been tests run which are above the average, where the results might be well above the average, and in a sense, skewing the averaged equation. But not really incorrect, considering the results would be one if not the most 'live' or up to the minute correct mean that can be found.
My basic Comcast connection is typically 11-12 Mbps (download) but this site claims it's "48% slower than the U.S. average (speed of) 22.6 Mbps."
Various articles conflict with that claim. Akamai, for example, listed the U.S. average speed as 16.3 Mbps in Q3 2016, which puts me at 3/4ths of the average, not 1/2. Peak speeds vs. averages may contribute to some confusion.
I don't mind being below other folk's speed, but I'd like to know where that "22.6 Mbps" figure comes from. Thanks.
