Efficiency is the ratio between what a [[System]] actually spends and what it physically must spend to [[Existence|Exist]].
A high $K_R$ means the [[System]] spends significantly more than its physical minimum. A $K_R$ close to 1 means the [[System]] operates near the limit of what is physically possible.

## RRT Formalization
**Ref:** [[Relational Resolution Theory (RRT)]], Section II.
**Logic:** $K_R = \Phi_{measured} / \Phi_{\min}$.
A dimensionless ratio measuring the gap between actual power and the [[Energy Floor|Landauer limit]].

## In the Equation
**"The Metric"** ($K_R$)
$K_R$ quantifies how far a [[System]] operates from its physical minimum. A $K_R$ approaching 1 means near-perfect efficiency; $K_R \gg 1$ means the [[System]] spends significantly more than required.
