## Observations
1. **RCA consistently outperforms E2E** in later weeks (Weeks 7–10), with a **12% higher accuracy** in Week 10 (`0.89` vs. `0.82`).
2. **E2E shows volatility** but stabilizes around `0.72–0.74` until Week 9, where it surges to `0.78`.
3. **RCA exhibits sharper fluctuations**, with a **16% drop** from Week 7 (`0.83`) to Week 8 (`0.75`), followed by a **16% recovery** in Week 9.
4. **Both methods start at similar baselines** (Week 1: `0.68` for E2E, `0.71` for RCA).
## Data Table Reconstruction
| Week | E2E Accuracy | RCA Accuracy |
|--------|--------------|--------------|
| week1 | 0.68 | 0.71 |
| week2 | 0.72 | 0.79 |
| week3 | 0.72 | 0.79 |
| week4 | 0.75 | 0.79 |
| week5 | 0.72 | 0.74 |

## Cross-Reference Validation
- **Legend Colors:**
- Blue (`●`) corresponds to E2E line (matches all blue data points).
- Orange (`■`) corresponds to RCA line (matches all orange data points).
- **Axis Markers:** All week labels (`week1`–`week10`) align with X-axis ticks.
- **Y-Axis Scale:** All data points fall within `0.70–0.85` range.
