Do this in order
- Prioritize upgrades that make lemons faster, sell for more, or remove repeated clicking.
- After each meaningful purchase, repeat the same timed route and compare the result.
- If no new upgrade button appears, check nearby floor, wall, roof, or decoration buttons before assuming the route is finished.
Ready to move on when
- The new purchase changed the next measured run.
- You checked hidden or decoration-gated buttons around the stand.
- You avoided buying unrelated late-game items before the stand is stable.
