**1) Why the Day 7 survey is high-value** - Completing a post-video survey is an active, intent-signaling action (not passive viewing): it indicates engagement depth and willingness to invest time — a strong qualifier for B2B training buyers. - 完成视频后问卷是主动行为，代表客户愿意投入时间并表达意向，比单纯观看更能说明采购潜力（尤其适合B2B培训决策者）。 **2) Why AI keeps the lead in C Pool** - Predicted score is 54 vs. a 60 threshold to move C → B. The model flags rising momentum but not enough cumulative evidence yet; staying in C preserves efficient nurturing until intent or fit signals compound. - 预测分54，仍低于C→B的60门槛。系统识别到“升温趋势”，但证据不足，暂留C池以低成本持续培育，待意向/匹配度信号累积后再升级。 **3) Precise nurturing actions to trigger now** - Trigger a lightweight, content-led touch: send a tailored case study + short needs-assessment follow-up tied to the survey answers; schedule a 15-min discovery call task for sales. - Hold the formal B2B proposal until score crosses 60 or a second high-value behavior occurs (e.g., demo request, pricing page, or repeat survey/asset download). - 触发轻量内容型触达：基于问卷答案发送定制案例+简短需求确认；为销售创建15分钟需求访谈任务。正式B2B提案暂缓，待分数过60或出现第二个高价值行为（如申请演示、查看报价、重复下载资料）再发。 **4) How this supports a 100-unit distribution inquiry** - The survey data qualifies training scope and buyer role, improving proposal accuracy and shortening the path from inquiry to quote. Systematic follow-up raises the odds of converting a 100-seat distribution request into a qualified pipeline opportunity with higher win rate and larger deal size. - 问卷数据可明确培训范围与决策角色，提高提案精准度、缩短从询盘到报价的周期；系统化跟进有助于把100人分销询盘转化为高质量商机，提升赢单率与单笔规模。
