Inventory what you have
List each resource and count what is safe to spend. Keep anything reserved for repairs or upkeep aside before entering the current amount.
Measure a typical run
Use completed runs to estimate yield. Include travel, crafting, and restocking when you measure how much you earn per hour.
Round runs up
If you need 300 units and a trip delivers 45, you’ll plan seven trips. Recalculate once you have a few more observations or if your route changes.
