Historical Baseline serves as the fixed reference period for Sleepgenic's versioned reports. Canonical reconciliation spans 145 calendar rows from November 23, 2025 through April 17, 2026: 80 scored nights, one time-only partial record, and 64 explicit missing nights. Missing observations remain visible and are not imputed.
Across the baseline window, the median Overall Score was 67.5, with a Quality Score of 74.0, Recovery Score of 75.5, and Duration Score of 72.0. These values create the fixed scoring reference for future versioned comparisons.
The sleep architecture baseline showed 1.25 hours of deep sleep, 0.81 hours of REM sleep, and 5.99 hours of total sleep. This establishes the structural reference for assessing whether future weeks are producing more restorative depth, better REM continuity, or simply longer sleep without proportional recovery.
The autonomic baseline showed a median HRV of 35.0 ms and resting heart rate of 65.0 bpm. These values are important because Sleepgenic does not treat sleep scores alone as the full truth. Versioned reports and interpretations compare surface-level scores against deeper physiological signals to determine whether the body is recovering, adapting, or carrying unresolved stress.
The baseline stress profile showed Sleep Stress of 17.2 and 44.0 restless moments. These markers provide the reference layer for identifying whether future weeks reflect true recovery, disrupted sleep, training load, environmental stress, or adaptation pressure.
This baseline is intentionally simple. It does not attempt to over-explain the past. Its role is to create the measurement floor for everything that follows. This fixed historical profile remains useful for long-range comparison. Canonical v1 also calculates rolling 28-day personal baselines from prior scored nights, excluding the current night, so recent deviations can be interpreted without replacing the historical reference.
