Intensity is only 7.6 (vs 9.76 last round) — big headroom. Let me use it: taller lift, deeper drop, more speed.

Done — banked at **6.79 excitement**. **Best coaster:** a 122-piece steel twister — 19-piece chain lift to z=440, a 288-unit triple-60° plunge (36 ft highest drop), then two half-loop→corkscrew combos and two vertical loops, finishing with airtime hills and banked 5-tile turns back to the station. Excitement **6.79**, intensity 8.46, nausea 4.38, no crash, similarity 0.38 (nearest: Viper). What drove the improvement over the previous 6.84-attempt's design (which had 3.02 lateral G): - Reading `RideRatings.cpp` showed `ride_ratings_get_excessive_lateral_g_penalty` fires hard above **2.80 lateral G** (+3.75 intensity, +2.00 nausea), and lateral-G *excitement* is capped at 1.50 — so the old build was paying a large intensity tax for zero gain. Replacing all unbanked 3-tile descending turns with banked 5-tile turns dropped lateral G to 2.73 and intensity from 9.76 → 8.46. - I spent that freed intensity headroom on a taller lift and a deeper first drop (max speed 1.45M → 1.65M, highest drop 26 → 36). Two caveats worth stating plainly: at 6.79 this is a hair *below* the 6.84 from the previous round, and I ran out of budget before exploiting the remaining ~1.4 intensity headroom. The clearest unspent lever I identified is `get_banked_turns_rating`, which is **uncapped** in count (unlike flat/sloped turns and inversions) at a ~2.3:1 excitement-to-intensity ratio — the 23 filler `flat` pieces in the two straightaways should be banked-turn S-curves. Also, the game counted only 4 inversions despite 6 inversion pieces, so the two vertical loops appear not to register; I didn't get time to find out why.
