**1) Why the Day 7 behavior is high value** - Completing a post-video survey is an active, self-declared signal — it reveals intent, topic interest, and buying context, not just passive viewing. - 完成视频后问卷属于主动表达，能暴露真实需求、关注主题和采购背景，比单纯观看更有价值。 - 中文：主动填写问卷说明客户愿意投入时间，是明确的兴趣信号，远强于被动浏览。 **2) Why AI keeps this lead in C Pool** - Predicted score is 25 vs. C→B threshold of 60 — intent is emerging but evidence is still thin (one high-value action, low cumulative engagement). - 预测分25，距C升B阈值60仍有差距——意向刚显现，证据不足（仅一次高价值行为、累计互动偏低）。 - 中文：系统判断为“有苗头但未成熟”，升级会过早消耗销售资源，留在C池继续培育更稳妥。 **3) Precise nurturing actions to trigger** - No proposal or sales follow-up yet; instead trigger a low-friction nurture sequence: targeted case study / training catalog for the surveyed topic, plus a soft qualification question. - 暂不发送B2B提案或安排销售跟进；改为触发轻量培育：按问卷主题推送相关案例/课程目录，并加入一个软性资格确认问题。 - 中文：先低成本养熟，用内容+提问继续收集信号；等分数接近阈值再升级。 **4) How this supports a 100-unit distribution inquiry** - The survey data qualifies scope (units, audience, timeline); as score climbs toward 60, the system auto-upgrades to B and triggers a tailored proposal and sales follow-up — positioning the 100-unit deal with evidence, not guesswork. - 问卷可确认规模（数量、受众、时间表）；分数逼近60时系统自动升B并触发定制提案与销售跟进，用数据支撑100套分销询盘，而非凭猜测推进。 - 中文：行为→分数→升级→动作→成单，每一步都有依据，提升大单转化率与销售效率。
