Resonance context

Calculated cartridge/tonearm resonance: 6.89 Hz, below the preferred 8–12 Hz region. No Vibration observation is associated with this RPM measurement, so combined Resonance × Vibration interpretation is not applicable to this record.

Scientific limitation: RPM/W&F values are mechanical motion-sensor observations and are not presented as standards-certified weighted wow & flutter.
