# Best Practices on Performance Cases

## Approach 1: Single case with graduation rates

**Level of Effort: Low**

Build only one case and the performance risk is captured in the *graduation rates* of the forecasted rounds.

## Approach 2: Multiple cases with 100% graduation rates

**Level of Effort: Low**

Build multiple cases and the performance risk of the investment is captured in the *case probabilities* of each case.

## Approach 3: Multiple cases with custom graduation rates

**Level of Effort: High**

Build multiple performance cases and the performance risk is captured in *both the case* *probabilities and the graduation rates* within each case. This gives you the greatest control - for e.g., you may model an Upside case that has a higher likelihood of graduations than the Base case.
