    "reasoning": "I've been trying to analyze volume vs AI performance correlation but keep hitting casting errors because the data has mixed row types (daily summaries AND individual call records in the same table). Let me reconsider what I've actually observed:\n\nFrom step-13, I have clean daily data for 30 days. Looking at the patterns:\n\n**High volume days (400+ calls):**\n- 24-Jun: 435 calls → 80.70% AI resolution\n- 23-Jun: 428 calls → 80.80% AI resolution  \n- 29-Jun: 434 calls → 75.00% AI resolution\n- 14-Jul: 427 calls → 76.10% AI resolution\n- 21-Jul: 423 calls → 77.10% AI resolution\n- 22-Jul: 417 calls → 76.50% AI resolution\n- 17-Jul: 413 calls → 80.60% AI resolution\n- 07-Jul: 400 calls → 73.20% AI resolution (LOWEST for high-volume)\n\n**Low volume days (under 150 calls):**\n- 04-Jul: 123 calls → 74.00% AI resolution\n- 05-Jul: 129 calls → 74.30% AI resolution\n- 11-Jul: 119 calls → 82.30% AI resolution (HIGHEST overall!)\n- 12-Jul: 117 calls → 76.40% AI resolution\n- 28-Jun: 116 calls → 75.80% AI resolution\n- 18-Jul: 114 calls → 76.70% AI resolution\n- 27-Jun: 130 calls → 78.70% AI resolution\n- 19-Jul: 138 calls → 76.60% AI resolution\n\nThe MOST SURPRISING finding: **July 11th had only 119 calls (one of the lowest volume days) but achieved 82.30% AI resolution rate - the SECOND HIGHEST in the entire 30-day period.** Only July 13th (350 calls, 82.80%) was higher.\n\nThis is counterintuitive because:\n1. Low volume days are typically weekends when caller intent might be more varied/complex\n2. You'd expect the AI to perform better with more 'practice' during high-volume periods\n3. Yet this tiny-volume day outperformed almost every high-volume weekday\n\nThe inverse is also striking: July 7th had 400 calls (high volume) but only 73.20% AI resolution - the LOWEST rate in the dataset. That's a 9+ percentage point swing from the best performer.\n\nThis suggests AI performance is NOT driven by volume, but by something else - likely the TYPE of calls received on different days (weekday vs weekend caller intent, specific events, seasonal patterns)."
