Compare two player-entered cart plans
Give each plan a name, then enter its cart, engine, and fuel counts. Add distance, cash, time, or offline observations only when you recorded them; the Planner compares the same valid metric and names any missing input.
For spending in Build A Cart, enter cash spent and observed distance to unlock distance per cash only when spend is above zero. For Build A Cart earnings, cash gained with positive run or offline time can unlock cash per minute or offline cash per hour. Results stay copyable observations, not official predictions.
