Claude (auto-RE) 6c7025851e re(flight): the rate probe measures a MOVING speed -- pitching bleeds it hard
Measured pitch with the rows properly pinned, against this craft's own disc caps
(AV_PitchPlus_Min 150, AV_PitchPlus_Max 70):

    min speed (LT)  1391.0 deg / 8.00 s, clock x1.326 -> 131.1 deg/game-s  vs 150
    max speed (RT)   989.0 deg / 8.05 s, clock x1.318 ->  93.2 deg/game-s  vs 70

A rate 33% ABOVE a cap is not a finding, it is a broken instrument. The HUD speed
is in the same bracketing screenshots that give the clock, so read it:

    slow phase   102 ->  18
    fast phase  1193 -> 589

The speed is NOT constant during the dwell -- pitching halves it in 8 seconds.
The cap is speed-dependent, so as the craft slowed its cap rose, and an 8-second
average necessarily lands between the max-speed cap and a mid-speed one. The 133%
is entirely the instrument.

This also weakens the roll result committed earlier: same method, so 120.9 vs
AV_Roll_Max 125 is CONSISTENT but is not a tight test -- the true cap could be
lower and still produce that average. Said plainly in the doc rather than left
standing as a clean confirmation. Min-speed figures are less affected; there is
little speed left to lose.

Proper fix, not yet done: dwell ~1-2 s so speed barely moves, or sample HUD speed
continuously and fit rate against INSTANTANEOUS speed -- which yields the whole
rate-vs-speed curve instead of two points.

Separately this is a flight-model finding: TURNING COSTS SPEED, steeply, with the
throttle still at maximum. A reimplementation treating the throttle as a speed the
craft simply holds will be wrong during manoeuvres.
