Your score, and what's actually in it.
Short browser tests that each return one number. Every result shows the raw measurement first, then how much of it your own display could be responsible for — because on a test this short, that share is not small.

A 60 Hz display can only change once every 16.7 ms, so the stimulus appeared somewhere inside that window rather than the instant it was requested. We show that band instead of quietly folding it into your score — and we don't invent a figure for the input path, because a web page can't measure it.
Raw score first
The number you produced, in the unit it was measured in, before any interpretation is applied to it.
No percentile we can't defend
Published reference ranges are cited and shown beside your score. Where none exists, you get no percentile — not an invented one.
Nothing stored
No account, no leaderboard, no results kept. Your scores stay on your machine.
