Route keyframes are (time, quat x4, pos x3), so each consecutive pair gives an implied speed. The flight-speed law was measured live against a real-time clock (cruise ~420, max ~1530 world units/s), which makes it an independent yardstick in known units. Across all 28 stage tables, 331 Route_* records and 1104 keyframe pairs: under SECONDS not one pair exceeds the 1530 ceiling (median 147); under frames at 30 or 60 fps, 89% and 94% of the game's routes would demand impossible speeds. Two corrections recorded. A first pass silently skipped non-numeric fields while flattening records, shifting every later value -- it reported a median implied speed of 65534, suspiciously 2^16, which is what exposed it. And the remaining outliers were Frame_S<NN>_Asteroid records, not routes; the final measurement filters by record kind rather than dropping whole stages.
