Use four questions before spending cash
What does it cost?
Record the exact cash cost currently displayed.
What does it say it changes?
Read the visible effect in your own game; do not infer it from the name alone.
What sale supports it?
Use a recent, measured wood sale as a baseline.
Can you repeat the test?
After one change, repeat the same route before crediting the purchase with a benefit.
Estimate sales from your own observations
Enter the last wood sale and the current visible plot cost in the calculator. The estimate tells you how many matching recorded sales would cover the cost; it never treats that as a promise about future earnings.
A plot name is not a benefit table
The game may show more context in play than the official description. Until a visible panel or repeatable test supplies it, this guide does not claim that a plot has a particular tree, yield, capacity, or cash effect.
After buying
Save the before-and-after session notes. If a change appears useful over more than one equivalent run, you have a personal decision record rather than an unsupported universal ranking.
Build the cash baseline first
A visible cost only becomes actionable after you know what one normal wood sale looked like for you.
