 ### Notes
 
 - Odyssey has poor support for extended query protocol in transaction pooling mode, resulting in significantly lower performance compared to pg_doorman and pgbouncer
-- Results may vary based on hardware and system load
+- **Important**: The values shown are **relative performance ratios**, not absolute TPS numbers. While absolute TPS values may vary depending on hardware and system load, the relative ratios between poolers should remain consistent when tests are run sequentially in a short timeframe (30 seconds each). This allows for fair comparison across different connection poolers under identical conditions
