How the test works
The oldest benchmark there is
The simple reaction time test measures one thing: how long it takes you to respond to a signal you're expecting. The panel sits red while a random delay of 1.5 to 5 seconds counts down — that randomness is what stops you from anticipating the switch. The instant it turns green, a hidden clock starts, and it stops the moment you click.
We run it five times and take the median, not the average. One lucky click or one distracted round shouldn't define your number — the middle value is a far more honest read of your true speed.

Questions
What counts as a good click reaction time?
For a simple visual click test, most people land between 200 and 300 ms. Consistently clicking under 200 ms is genuinely fast — top-5% territory.
Why does it say “jump start” when I click?
You clicked while the panel was still red, before the green signal. That is anticipation, not reaction, so the round is voided and restarts with a fresh random delay.
Why the median of five instead of my best round?
Your single best click is usually a lucky outlier. The median throws out the flukes at both ends and reflects the speed you can actually repeat.
How is the timing so precise?
The green signal is stamped at the exact frame your screen paints it, and your click is caught on pointerdown, both using the browser high-resolution clock. Your display and mouse still add a little unavoidable latency.
