Time scoring
How we score time memory
Targets are seed-generated pseudo-random time intervals. Easy rounds draw 1000-3500ms intervals; harder rounds draw from 500-6000ms with long intervals spread across the run.
Not a neurological test The round score maps log-ratio timing error onto a 0-10 assessment score. The log/ratio basis follows timing psychophysics; the exact 0-10 curve is product calibration.
What the report uses
- Target interval in milliseconds.
- Your reproduced interval in milliseconds.
- Absolute error, relative error, and signed early/late bias.
- Consistency across five rounds and short-vs-long interval sensitivity.
Limits
Input device latency, browser frame timing, attention, audio/visual lag, and refresh rate can change timing results.
