- **Day 7 survey = explicit intent signal, not passive browsing.** Completing a post-video survey shows active engagement and willingness to share needs, which is a stronger buying signal than views alone. **中文：** 第7天填写问卷是主动表达意向，不是被动浏览；愿意分享需求，比单纯看视频更接近采购信号。 - **Score rises to 25, but C→B threshold is 60, so AI keeps lead in C Pool.** The behavior improves qualification, but the gap to upgrade is still 35 points; upgrading now would weaken pool discipline and waste sales capacity. **中文：** 分数升到25，但C升B门槛是60，所以AI暂不升级；差距仍有35分，过早升级会降低池子规则的有效性，也浪费销售资源。 - **Trigger low-cost, high-learning nurture actions, not direct sales handoff.** Recommended: send tailored training brochure, case study, and a short needs-assessment follow-up; tag survey answers for topic/pain-point segmentation. **中文：** 触发低成本但高信息量的培育动作，而非直接转销售；建议发送定制培训手册、案例和简短需求确认，并用问卷答案做主题/痛点标签。 - **Use survey data to build the business case for a 100-unit distribution inquiry.** If the lead shows multi-team or channel-partner demand, route to SDR for qualification and prepare a volume-based proposal outline. **中文：** 用问卷数据构建100套分销询盘的商业理由；若显示多团队或渠道伙伴需求，转SDR做资格确认，并准备批量报价方案框架。 - **Business outcome: better pipeline quality, not faster but weaker conversion.** Keeping the lead in C Pool until score ≥60 improves conversion efficiency, protects sales time, and increases likelihood of a larger deal. **中文：** 业务结果是提升商机质量，而不是追求更快但更弱的转化；分数到60前留在C池，可提高转化效率、保护销售时间，并提升大单概率。
