| "key_insights": [ |
| "TwoSidedDual wins EVERY price condition and budget level — 2.3× more clicks than DualOGD", |
| "Optimal epsilon for TwoSidedDual: ε=0.003 (low) — needs slow, stable pacing", |
| "Optimal epsilon for DualOGD: ε=0.03 (high) — needs fast adaptation since it only has cap constraint", |
| "k=0.95 is optimal for TwoSidedDual — near-full budget utilization matters most", |
| "Low-competition markets give 3-4× more clicks than high-competition (292 vs 170 for TwoSidedDual)", |
| "ValueShading is 42% behind TwoSidedDual — closed-form shading can't match grid-search optimization" |
