Human PrecisionHuman Precision is an endurance game built around a narrow question: how long can you keep a cursor-controlled point out of trouble while the visual field becomes faster and less forgiving?
The score mixes several abilities
A run is not a pure measure of reaction time. You are continuously reading space, predicting where each opening will arrive, choosing a path, and making small motor corrections with a mouse or trackpad. Attention, visual processing, hand-eye coordination, device latency, pointer settings, display refresh rate, and familiarity with the game can all affect the result.
Why distance works
Distance is a simple game score rather than a diagnosis. The wall stream accelerates with time, so surviving longer also means surviving a harder version of the same task. That makes personal bests easy to understand without pretending that the number maps cleanly to intelligence, health, or athletic ability.
Keep comparisons fair
If you want to compare your own runs, keep the setup consistent. Use the same computer, browser, display, mouse, pointer sensitivity, and general environment. A change in hardware can change the input path enough to make an old baseline less useful.
What it does not prove
A high score does not establish a medical condition, cognitive capacity, professional aptitude, or real-world safety level. Human Precision is a recreational browser challenge. Improvement may reflect better anticipation of the gap sequence, better mouse control, or simple task familiarity.
