- 1x to 1.99x: stable bonus zone for normal farming.
- 2x to 2.99x: strong multipliers worth keeping if inventory pressure allows.
- 3x and above: premium targets. Prioritize survival and clean extraction.

Run Management Tips
- Keep one slot policy for premium catches so accidental drops are less likely.
- If oxygen is low, cash out high multipliers first before extending route depth.
- Rebuild route stability around consistent 1.6x-2.5x outcomes, then chase jackpot rolls.
