Cleanest linear measurement: neutral throttle (HUD = CruisingVelocity 350), sticks
centred, 20 s of perfectly straight flight (displacement/path = 1.000):
8 900 world units in 20.1 s -> 443.6 /s -> 1.267x the HUD's 350
And the game's own mission timer across a wall-clock interval:
TIME 00:08.79 -> 00:46.97 = 38.18 s of game time in 30.29 s wall = 1.260
Same number. So the linear discrepancy is not a unit difference: the mission clock
runs ~1.26x faster than wall time under this emulator, and dividing world
displacement by WALL seconds inflates speed by exactly that. World units and
displayed speed share one unit; the definition velocities are per GAME second.
This supersedes the previous "world-unit vs displayed-speed" reading.
Left open (❔): settled turn rates measured 74.9/41.1 deg/s in wall time against
AV_PitchMinus_Min/Max 75/40, but the clock argument predicts ~94 for the first.
Either that agreement was luck inside a noisy sample (per-window rates spanned
61-96) or angular integration is frame-based where linear is time-based. The check
is to re-measure pitch and convert wall->game seconds with the clock ratio.
