The upload speed numbers are highly suspect. I have cable that shows 32Mbps on every test I've ever run and yet CF is showing an absurd 221Mbps

[edit]

I saw the more detailed information below. The high speed comes entirely from 2 outliers on the 1MB upload test; all of the 10MB tests were clustered around 32Mbps

[edit2]

I reran and got similar results again with 3 1MB uploads over 200Mbps and all other uploads clustered around 32Mbps
