Scoring principles
Repeated trials reduce the effect of a lucky press. Accuracy penalties prevent uncontrolled speed from carrying a task. Consistency adjustments reward repeatable performance.
Full daily challenge weights
| Skill | Weight | Main inputs |
|---|---|---|
| Reaction | 20% | Median response and variation |
| Timing | 15% | Average absolute interval error |
| Accuracy | 15% | Target speed, misses and consistency |
| Memory | 20% | Correct ordered sequence points |
| Focus | 15% | Hits, omissions, false presses and speed |
| Rhythm | 15% | Average distance from expected beats |
Official daily score
The first completed six-skill run on a local calendar day becomes that browser’s official score for the day. The daily challenge uses date-seeded variation so it changes automatically without manual scheduling. The official score cannot be replaced by a later practice attempt.
Quick Check and Practice Mode
The one-minute version uses reaction at 40%, timing at 30% and visual accuracy at 30%. Full Practice Mode uses all six daily weights. Neither mode replaces the official daily result or extends a streak.
Hardware and browser effects
Display refresh rate, input polling rate, touchscreen processing, browser scheduling and operating-system latency affect online timing. The cleanest personal comparison uses the same device, browser and input method. Human Precision labels results by broad device and input category rather than pretending all hardware is equivalent.
Interpretation limits
- The tests are recreational and browser-based.
- They are not designed to diagnose ADHD, dementia, concussion or another condition.
- They do not measure general intelligence. The separate IQ-style assessment has its own methodology and limitations.
- Practice effects are expected.
- Broad claims about school, work or health improvement are not supported by these scores.
