Seems oddly low. I know the US is notorious for low speeds, but 3.35 Mbps for Google fiber? Does their measurement actually measure what I intuitively think measures? I've used two different ISPs in recent years and both sustained 10+ Mbps over long periods of time with their mid range tiers, and had basic tiers offering 3 - 5 Mbps which I believe performed as rated. While I know that most of the country is likely on slow Internet, I have a really hard time seeing how the numbers end up lower than ~5 Mbps avg overall unless the whole situation is way worse than I ever suspected and that large portions of the sample were either mobile users or rural.
