ROI decision rules
A practical checklist before buying the next weight.
| Upgrade if | The next weight consistently reaches a better zone stage. |
| Wait if | The price delays every other upgrade and your current zone is still profitable. |
| Skip if | The upgrade does not change zone reach or tsunami consistency. |
| Pair with | Run speed, mutation target, and zone planning before rare-roll sessions. |
Best next move
Buy the upgrade that changes where your block lands. If the next weight only makes the same zone slightly cleaner, compare mutation odds or save for a bigger route jump.
