<b>Why Google uses your 75th-percentile visitor</b>

Here's a number that quietly decides whether you pass: the 75th percentile. When Google judges your Core Web Vitals, it doesn't use your average visitor or your best one — it lines up all your visitors from fastest to slowest and picks the one three-quarters of the way down.

Why that one? Because an average can hide pain. If most visitors are fast but a quarter suffer, the average looks fine while real people struggle. The 75th percentile makes sure your <i>typical-to-slow</i> visitor still has a decent experience.

Think of it as grading a group hike by the person near the back, not the average pace.

What this means for you:
— A fast office laptop won't reflect your real score
— Test on a mid-range phone and throttled network to mimic that slower visitor

<b>Try this:</b> In DevTools, set the network to 'Slow 4G' and CPU to '4x slowdown', then retest. You're now seeing roughly who Google grades you on.
