This URL redirects to https://microsoft.github.io/TypeChat/.

The same URL in a different form — a trailing slash — so both are treated as one site rather than two: one history, measured once. Lighthouse follows the redirect, so the numbers below describe the page actually served; the only cost is an extra hop on each run.

Lab LCP vs Field LCP Chrome UX Report

Lab 1.06 s

Field p75 1.68 s

The lab LCP is 0.63× the field p75 — real users likely have below-average hardware or network connectivity. A gap this wide usually means real users are on slower devices or networks than the simulated ones — the lab number is flattering you.
