    Best banked result: a 76-piece steel twister — 176-unit chain lift into a steep first drop, then a rolling-hill circuit with two vertical loops and two corkscrew U-turns (4 inversions, 11 drops, 71 air-time, max speed ~1.41M) yielding **excitement 6.52**, intensity 9.86, similarity 0.465 (no penalty).
