Fitting rate against instantaneous speed produced a tidy "rate rises with speed" relationship, with speeds up to 4795 when the craft's maximum is 1200. It is entirely an artefact: 20 Hz polling is faster than the guest updates these fields, so a per-read delta is either exactly zero (no update yet) or a whole frame's worth divided by a fraction of a frame. 111 of 352 reads were zero on BOTH channels -- position and attitude update on the same frame, so the two are perfectly correlated, and dividing each by the short wall dt produced the correlation out of nothing. Fix: aggregate over windows spanning many frames (0.5 s). A sum of |delta| over such a window is right however the updates fall inside it. This does NOT affect the swept-total probes (roll_axis.py, rate_probe.py) -- they already summed over the whole dwell, immune for the same reason. Only per-sample instantaneous rates were ever wrong, so no earlier number moves. The windowed re-run is NOT yet claimed as a result. It gives plausible magnitudes but still shows rate rising with speed, against the definition's PitchPlus_Min 150 > _Max 70, and it has two disqualifiers: it ran on an instance where the craft was already tumbling from the previous sweep, so pinning reported "WEAK -- craft may not be level", and the sweep started mid-range rather than at maximum. A clean answer needs a fresh flight with pinning CONFIDENT and nothing before it. Since what is in doubt is precisely what _Min/_Max mean, a measurement through a doubtful instrument cannot settle it. Both datasets kept, the bad one labelled, because the aliased curve is a good example of what a manufactured correlation looks like.
