**1) Why the Day 7 behavior is high value** - Completing a post-video survey signals active engagement and intent, not passive viewing—this is a strong qualifier for training needs. - 完成视频后问卷代表主动参与和明确意向，而不仅仅是被动观看，是判断培训需求的高质量信号。 **2) Why AI keeps the lead in C Pool** - Predicted score 33 vs. C→B threshold 60: intent is rising but not yet strong enough to justify upgrade or sales handoff. - 预测分33，远低于C→B升级线60：意向在上升，但还不足以触发升级或转交销售。 **3) Precise nurturing actions to trigger** - Send a personalized thank-you email referencing survey answers + a relevant case study or micro-demo. - Add to a light-touch drip sequence (2–3 emails over 7–10 days) designed to push score toward 60; flag for manual review only if score jumps >15 in one session. - 发送个性化感谢邮件（引用问卷回答）+ 相关案例/微演示；加入7–10天的轻量邮件培育序列，目标把分数推向60；仅当单次分数跃升>15时才转人工复核。 **4) How this supports a 100-unit distribution inquiry** - Consistent, relevant nurturing builds credibility and keeps Global Skills top-of-mind, increasing the odds the lead converts into a bulk distribution request. - 持续、相关的培育建立信任并保持品牌优先记忆，提高该线索转化为批量分销询盘（100套）的概率。 **Core logic:** Behavior → Score lift (30→33) → Below 60 threshold → Stay in C Pool → Automated low-touch nurture → Gradual intent build → Sales-ready for 100-unit inquiry. **核心逻辑：** 行为 → 分数提升（30→33） → 未达60阈值 → 留在C池 → 自动化轻触达培育 → 意向逐步累积 → 最终具备100套询盘的销售转化条件。
