What LCP is made of observed, unthrottled
A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.
Measured on the trace before throttling is modelled, so these are real durations that will not sum to the 1.21 s above — that figure is a simulation of the same load on a slow phone and connection. Read these for the proportions: which phase dominates.

Lab vs field
Lab LCP 1.21 s · field p75 1.96 s · real users are 1.62× slower than the lab. A gap this wide usually means real users are on slower devices or networks than the simulated ones — the lab number is flattering you.

Axe violations axe-core 4.13.0, full rule set
1 violating node across 1 rule, 348 passing. This is a standalone axe run, stricter than the subset Lighthouse folds into its score above — and it is the second tiebreaker in the ranking.
