   $$\eta = \frac{A_{catch} \cdot R}{1 + k \cdot \Delta H^2}$$
   Where $A_{catch}$ is the surface area of collection, $R$ is the local precipitation rate, and $k$ is the Coefficient of Surface Adhesion Damping (SAD)/), a value determined by the reflectivity of the catchment material. Materials with high inherent sadness, such as dull grey slate, exhibit lower [SAD coefficients](/ent…
