 ### Benchmark Methodology
 
-Benchmark executed on **Raspberry Pi 4 (4GB)** using 3 bilingual prompts (mixed Italian/English).
-Average eval rate calculated from `eval rate:` logs only, excluding load and warm-up time.
-Runtime: Ollama 0.x on Raspberry Pi OS (Debian Bookworm).
+- **Duration**: 60.1 minutes (3,603 seconds)
+- **Total requests**: 455 (2-second interval)
+- **Platform**: Raspberry Pi 4 (4GB RAM, ARM Cortex-A72 @ 1.5GHz)
+- **Runtime**: Ollama 0.3.x + llama.cpp backend
+- **Monitoring**: CPU temp, RAM usage, load average (sampled every 5s)
+- **Tasks**: Performance (128/256/512 tokens), Quality (HellaSwag, ARC, TruthfulQA), Robustness (soak test)
 
-> **Recommendation**: Use **Q4_0** as default (3% faster, 82MB smaller, equivalent quality). Use **Q4_K_M** only if you need slightly better coherence in very long conversations (1000+ tokens).
+> **Recommendation**: Use **Q4_K_M** for production deployments (proven 100% reliability over 60 minutes). Use **Q4_0** for development/testing if you need slightly faster inference.
