Questions
Why the median instead of the average?
One distracted click can pull an average far from your normal speed. The median is the middle of your five valid attempts.
Can a website measure my monitor or mouse lag?
No. A browser cannot separate your reaction from your hardware. We show your browser's render pace and state that limit plainly.
Does this say anything about my health?
No. This is a game-style test, not a medical assessment. If you notice a sudden change in your reactions, speak to a medical professional.
