Primary results

Metric	Result
Settled frequency	992.88 Hz
Playback speed error	-0.71%
Calculated speed	33.10 RPM
DIN-weighted wow & flutter	0.045%
Average 1 kHz separation	30.4 dB
Channel balance	-0.63 dB
Combined 1 kHz THD	0.31%

Playback speed and rotational stability were measured consistently during the capture. Channel-specific distortion, harmonic, balance, and directional crosstalk results require repetition before mechanical adjustment.
