Lighthouse 13.5 (mobile, simulated throttling), median of three runs. Scores 0–100: 90 and up green, 50–89 orange, below 50 red; a dash means the category was not measured in that check.
TBT is the lab stand-in for INP, which needs real interactions.

Google PageSpeed Insights: Comparison details
Vitals Desk is the primary measurement. Google adds one mobile lab run from its servers. This comparison does not change our scores, history or slowdown emails.
The measured values have no substantial differences.
The Lighthouse versions differ; scores and checks may not be directly comparable.
Different locations, hardware, Lighthouse versions and a single run versus our three-run median can produce different results. These are comparison notes, not regression alerts.
