## 📊 Wave C vs Wave D
|
|
|
|
| Metric | Wave C (201) | Wave D (225) | Overhead |
|
|
|---|---|---|---|
|
|
| **Features** | 201 | 225 | +24 (+11.9%) |
|
|
| **Latency** | 3.91μs | 3.98μs | +70ns (+1.8%) |
|
|
| **Efficiency** | - | - | **6.6x better** |
|
|
|
|
**Conclusion**: Only 1.8% latency increase for 11.9% more features = 6.6x efficiency
