Live progress comes from a direct browser-to-node download. It reflects your current path to that region and does not mix in a server-side proxy speed.

Local mode reports TCP/HTTPS round-trip latency, not ICMP Ping. The request starts from your browser and is not measured by a server-side proxy.

Each test measures a different path or protocol. Interpret results separately and run one test at a time to reduce interference.
