How we measured this

  1. 1. We fetched your page and scored it with PageSpeed Insights (mobile, lab data).
  2. 2. We re-fetched it through a Turbulence preview environment that applies our transformation pipeline.
  3. 3. We scored the result with PageSpeed Insights again.
  4. 4. The deltas above are the difference — a directional estimate, not a forecast. First visits, geographic location, network conditions, and JS-rendered content all affect real-world results.
