Fast answer: the best Sky Zoo upgrade order
Start with stable captures, then capacity-style upgrades, then income or stamina boosts, and only then expand into new slots or harder routes. That order avoids pretending this fan hub knows every current economy value while still giving beginners a reliable decision model.
The common beginner mistake is buying the most exciting visible upgrade instead of the upgrade that improves the next ten runs. A small, repeatable improvement can beat a flashy new slot that sits underfilled because you cannot yet capture enough animals to support it.
