Core Web Vitals
LCP, INP, CLS, and TTFB for this page, next to the 75th percentile of the web vital events already stored.
This visit and the stored sample
LCP, INP, and CLS use the same cutoffs as the Collection Lab: 2.5s and 4s for LCP, 200ms and 500ms for INP, 0.1 and 0.25 for CLS. TTFB is responseStart − requestStart on the navigation entry, with cutoffs at 800ms and 1.8s. The p75 column is the nearest-rank 75th percentile of the latest 500 web_vital rows. Those rows are written on the Collection Lab when consent is on. TTFB is not one of those stored metrics, so its sample stays empty until a row uses that name.

Where these numbers meet engagement
A slow largest paint or a slow interaction is time the visitor is not scrolling or reading. The intent score is built from scroll, dwell, return visits, and pages. The beacon that stores a web vital is sent from the Collection Lab.
