What this actually tests
This measures the time between a visual change (the box turning green) and your click reaching the browser — a rough proxy for simple visual reaction time. Typical human reaction time to a visual stimulus is around 200-250ms; competitive gamers often land in the 150-200ms range. Display lag, input lag from a wireless mouse, and browser performance all add a small amount of overhead on top of your actual reflexes, so treat this as a consistent comparison tool rather than a lab-grade measurement.
Getting a fair reading
- Rest your hand on the mouse before starting — the first round often measures "getting ready," not reflexes.
- Run it a few times; reaction time naturally varies round to round.
- A wired mouse and a wired or low-latency display will read faster than a laggy wireless setup, independent of your actual reflexes.
