How this list is built
Latency here is the full round trip of a relayed request measured at check time, not a raw TCP connect. Treat it as a ranking signal rather than a guarantee: a free proxy that was fast a minute ago can be saturated now, so always keep a timeout and move to the next entry on failure.
