Run a baseline sales cycle
Order trees, place them in the lot and serve customers while you note the starting cash, reputation and stock. After a short session, record the change in reputation and the number of sales. If the interface separates goals, boosts or bonus rewards, track those separately so you can compare ordinary sales.
Restock before expanding
Watch what happens when a customer arrives. If trees are frequently missing, spend your next round of cash on keeping stock available. If a tree type sells slowly, try a smaller order next time and keep more cash for your faster sellers.
Hire for the task that interrupts sales
Check the available worker roles and read their duties before buying. If you are leaving customers waiting while you replenish trees, prioritize a worker who can cover the task pulling you away. If customers are already moving smoothly through the lot, save the cash for your next order or expansion.
Compare two equal sessions
Change one variable, such as the worker you assign or the trees you stock. Compare reputation gained per minute and cash left over in two runs of the same length. If a run includes a limited boost, use the same boost in both runs or compare with unboosted sessions.
