+
+## Foundational SAAQ Equation
+
+The current foundational SAAQ equation relies on an L2 Normalized Voltage Bound:
+
+$$V_{\text{norm}} = \frac{V}{\sqrt{\sum V_i^2 + \epsilon}}$$
+
+## Variable Breakdown
+
+- **$V_{\text{norm}}$**: The bounded, normalized voltage
+- **$V$**: The raw, unscaled voltage vector
+- **$V_i$**: The individual voltage components used to calculate the Euclidean length
+- **$\epsilon$**: A small constant added to the denominator to prevent division by zero
