- **Why Day 7 matters:** Repeated viewing of the Cultural Insights Demo signals active, topic-specific interest — a stronger buying signal than a single click, but early-stage. 这一步说明客户对文化主题有持续兴趣，属于积极信号，但还只是早期探索。 - **Why still in C Pool:** The predicted score of 6 is far below the C→B threshold of 60, so AI treats it as a low-confidence signal and avoids premature upgrade. 预测分仅6，远低于60的升级线，AI判断信号强度不足，暂不升级以免误判。 - **Nurture actions to trigger:** Send a short, targeted follow-up (demo recap + relevant case study), and schedule a soft sales touch in 3–5 days — no formal proposal yet. 触发动作：发送精准跟进（演示要点+相关案例），3–5天后安排轻量销售触达，暂不正式提案。 - **Path to the 100-unit inquiry:** Sustained repeat engagement + content depth will compound the score; once it approaches 60, upgrade to B and trigger a tailored B2B proposal. 持续深度互动会累积分数；接近60时升级到B池，并触发定制化B2B提案，为100套询盘铺垫。 - **Business rationale:** This filters noise, protects sales capacity, and concentrates effort on genuinely maturing leads — improving pipeline quality and conversion efficiency. 这样能过滤噪音、节省销售资源，把精力集中在真正成熟的线索上，提升商机质量与转化效率。
