Understanding Your Metrics
Max Level (Digit Span)
The highest number of digits you successfully recalled. This measures your visual digit span — the capacity of your short-term memory for numerical sequences.
Accuracy
The percentage of trials where you correctly recalled the number. Higher accuracy indicates more reliable memory recall.
Overall Score
A composite score (0-100) based on max level (80% weight) and accuracy (20% weight). Uses logarithmic mapping with 9-digit span as the 50-point anchor.
Data Quality
Indicates the reliability of the test result. High quality requires a complete test with 5+ trials. Incomplete or short tests may produce less reliable scores.
