Notes

The whole release: each correction is a whole number of 16 ms samples in either direction, often two at once: 8,077 corrections, median −16 ms, p10–p90 −144 to +144 ms, p5–p95 −176 to +176 ms. The pilot (How often each device is corrected) gave +8 ms median (−64 to +80 ms). These steps do not track the Primus drift (Primus drift against the recorder PC, from breath matching).
