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.
Substantial differences: TBT
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.
