    "reasoning": "I have daily call volume and AI resolution data, but to identify the most surprising finding I need to look deeper at patterns that contradict expectations. The evidence shows AI resolution rates varying from 73-83%, with 'Today' showing 74.6% despite being a recent day. I should examine the relationship between call volume and AI performance, and look at the unnamed columns which appear to contain additional metrics (the ranges suggest they hold Duration, Sentiment data based on the header rows visible in step-3). Let me query to understand what's in those unnamed columns and check for counterintuitive patterns.",
