+## Tuning EMA alpha for inference time smoothing
+
+The `offloading_algo.ema_alpha` parameter in `settings.yaml` controls how inference
+times are smoothed. This affects offloading decisions:
+
+- **Lower values (0.1-0.3)**: More stable estimates, slower to adapt to performance
+  changes. Use when device performance varies slowly (e.g., room-temperature hardware).
+- **Higher values (0.7-0.9)**: Faster adaptation to sudden changes. Use when devices
+  may experience varying thermal conditions or network quality.
+- **Default (0.5)**: Balanced responsiveness for typical deployments.
+
+Changes take effect at server startup. For runtime tuning, use the environment
+override pattern with `SCIOT_SERVER_EMA_ALPHA` before starting the server.
