Copy the sentence that explains formula-based CPM vs static CPM.

There are two key sentences that explain the difference between formula-based and static CPM:
1. When "Use Percentile" is Disabled:
> If "Use Percentile" is disabled, the system does not apply any percentile logic. Instead, the existing CPM logic is used based on either:
> - A static CPM value, or
> - A formula defined in the configuration.
2. Usage of Percentile Config:
> The Percentile configuration is designed to work with both Static and Formula CPM floor types.
Would you like me to elaborate on the differences between static and formula-based CPM calculations?

I'll elaborate on the differences between static and formula-based CPM calculations based on the documentation from the [CPM Percentile Configuration](https://tripledotstudios.atlassian.net/wiki/spaces/KB/pages/4244537368) document.
**Static CPM**:
- A fixed, manually set floor value
- Simple and straightforward
- Does not change dynamically
- Set directly in the configuration
- Used when you want a consistent, predetermined CPM floor
**Formula-Based CPM**:
- Dynamically calculated based on recent ad events
- Uses historical CPM data from analytics buckets
- Calculates CPM using:
1. Events from selected buckets (MAX, Google, Meta)
2. A defined number of most recent events
3. A calculation method (e.g., average, median)
4. An optional coefficient for adjustment
**Key Differences**:
1. Flexibility:
- Static: Fixed value
- Formula: Adaptive based on recent performance
2. Data Sources:
- Static: No data used
- Formula: Uses CPM data from MAX, Google, and Meta buckets
3. Calculation Method:
- Static: No calculation
- Formula: Averages/medians CPM values, can apply a coefficient
**Example Calculation** (from documentation):
For a formula-based CPM:
- Events in bucket: 5, 6, 5, 5
- Calculation: (5+5+5+6)/4 × 1.1 = 5.775
- Final CPM floor = 5.775
Would you like me to dive deeper into any specific aspect of these CPM calculation methods?
