<summary><h4>▶ Step 1: Select MVL to Calculate</h4></summary>
Reference the flow chart to identify whether an <strong>MVL</strong> or <strong>MVL~a~</strong> is appropriate for your calculation, and whether a referent interpolator is required.

  - **MVL**: Assesses both model accuracy and variability for stochastic models  
  - **MVLa**: Assesses only model accuracy for deterministic models
