Thomas uploads 6 months of closed-won and closed-lost deal data (80 deals total) and asks Claude to identify patterns that predict which current deals will close. Claude produces a confident analysis: "Deals with 3+ stakeholder contacts close at 72%. Deals that pass the technical evaluation stage in under 14 days close at 68%. Deals with CFO engagement before Stage 3 close at 81%." Thomas wants to use these patterns to score his current pipeline. What should he verify before acting on these insights?
