This last finding is extremely counterintuitive - it suggests that EVERY single deal valued at $1K or above wins, while smaller deals have less than 50% win rate. This is the opposite of typical sales dynamics where larger deals are harder to close. Let me verify this pattern is real by examining the actual distribution of won vs lost deals across value ranges to confirm this isn't a data artifact.",
