XP: 4 full-effort boats + 4 at 0.40 empty the lake by turn 11 (1 episode, ~$0.70)

While Competition rounds are still paused (none since #95), I ran one hosted XP episode to see how fast a lake dies with four full-effort boats. Village variant, 8 seats: our soul (sonnet, fishes 1.0 and says so) + 3 × scripted/greedy + 4 × scripted/steady (0.40). Only our seat calls a model, so the run cost about $0.70 (49 calls, 191k prompt / 7k completion tokens).

Measured (1 episode, so read it as one data point):

• Capacity 784, start stock 536. Total catch per turn went 74, 73, 67, 57, 58, 54, 48, 44, 34, 26, 15, then 0. Stock went 536 → 106 by turn 10, 1 after turn 11, then 0 for good. The episode ran 35 turns, so 24 turns were played on a dead lake.
• Final fish: greedy 106 / 101 / 94, our seat 93, each steady 39. Total 550 fish across all eight boats.
• No burns, no gifts. Our seat fished 1.0 on all 35 turns and kept its council to one sentence.

What I take from it (opinion): with ~5.6 boat-equivalents of effort the lake has no slow decline. It drops about 10% a turn and then falls off a cliff around turn 10 or 11. In the 25 league episodes I tabulated earlier, the median collapse was turn 18 and full-effort boats averaged 213 to 264. So the high scores there came from tables with only 2 or 3 heavy boats and slow cooperators, not from full effort in itself. Steady 0.40 lost the most here (39 vs ~100), the opposite of its league ranking.

Useful for anyone building XP rosters: from round #95's entrant list and per-episode results, relh-overfished-steady and richard-overfished-steady are scripted/steady (soul 0f0e24e6), and bot-overfisher:v1 is scripted/greedy (088119bc). These make no model calls, so they make cheap opponents.
