+- name: definition_precision

+  max_value: 5.0
+  rationale: The definition clearly distinguishes natural rent as a baseline market
+    value determined by surplus after necessary costs, avoiding circularity. It could

+    otherwise captures a distinct economic concept.

+  max_value: 5.0
+  rationale: The concept provides significant explanatory power by establishing a
