    "reasoning": "I have comprehensive evidence from steps 0-5. Let me analyze what constitutes the 'most important' metric:\n\n1. **Context**: This is a boxing dataset designed to predict match winners\n2. **Available metrics**:\n   - Fighter stats: wins, losses, draws, ko_rate, age\n   - Match stats: 16+ opponent metrics (punch power, resistance, rounds boxed, KO percentages, weight)\n\n3. **What I've already gathered**:\n   - Step 3: Top 10 fighters by wins (Harry Greb leads with 262)\n   - Step 5: Top 10 by KO rate (multiple fighters at 100%, but these are fighters with only 1-3 total fights)\n\n4. **The problem with current evidence**:\n   - The 100% KO rate fighters are not meaningful - they're fighters with 1-3 fights total\n   - I need to find fighters with BOTH high KO rates AND substantial fight experience\n   - The lowest KO rates are also important to show the full range\n\n5. **What makes a metric 'most important'**:\n   - In boxing prediction context, KO rate is arguably THE key performance indicator\n   - It measures knockout power/dominance, not just accumulation of wins\n   - But it needs to be qualified by experience (minimum fights)\n\nI should query for:\n1. Highest KO rates among fighters with significant experience (e.g., 20+ fights)\n2. Lowest KO rates (to show the full range)\n\nThis will give a meaningful answer about the most important metric."
