Frequently Asked Questions
Why does my real download take longer than the estimate?
This is a theoretical estimate that assumes a steady, uninterrupted connection with no overhead -- real-world speeds are usually somewhat lower due to network conditions and protocol overhead.
Does this account for upload vs download asymmetry?
No -- enter whichever speed (upload or download) is relevant to get that direction's estimate.
