**Day 7 Behavior Is a Strong Buying Signal** Requesting a callback is an active, first-party intent action—not passive browsing. It signals the lead wants human contact, a key inflection point in B2B training deals. Day 7 主动申请回电属于高意向行为，说明客户已从"观望"转向"希望沟通"，是 B2B 培训成交的关键转折点。 **Why C → B Upgrade at Day 7** Score jumped from 55 (Days 1–6 cumulative) to 77 on Day 7 prediction, crossing the 60 threshold. The AI treats intent-based actions as stronger than volume of views, so an upgrade is justified. 分数从 55 跃升至 77，越过 60 阈值；AI 认为"主动行为"权重高于"浏览频次"，因此触发升级。 **Triggered Nurturing Actions** - Route to success/sales team for callback within SLA (e.g., 24h). - Send a tailored B2B proposal or training curriculum outline. - Create a follow-up task and log the interaction for pipeline tracking. Chinese: - 按 SLA（如 24 小时内）将线索派给销售/客户成功团队回电。 - 推送定制化 B2B 方案或培训课程大纲。 - 自动生成跟进任务并记录互动，纳入销售管道。 **Path Toward the 100-Unit Distribution Inquiry** At 77 vs. an A threshold of 120, the lead sits in a high-potential B tier. Sustained engagement plus proposal follow-up can push it toward A, where enterprise-scale (100-unit) conversations become sales-ready. 77 分离 A 池阈值 120 仍有空间，但已进入高潜 B 层；持续互动加方案跟进可推动升级至 A，届时 100 单位的分销级商机才具备成交条件。 **Business Impact** Faster, behavior-triggered routing shortens sales cycles and improves pipeline quality—fewer cold leads, more qualified distribution opportunities. 基于行为的自动流转可缩短销售周期、提升管道质量，减少冷线索，提高大额分销商机的转化率。
