+### Scaling of weight estimates
+
+Performs an additional scaling of weight compression estimate used by Vela to estimate SRAM usage.
+Increasing this scaling factor will make the estimates more conservative (lower) and this can result
+in optimisations that use less SRAM, albeit at the cost of performance (inference speed).  
+**Type: Float**  
+**Default: 1.0**  
+
+```bash
+vela network.tflite --weight-estimation-scaling=1.2
