1) **Day 7 behavior is high-value because it shows “intent acceleration.”** Repeat engagement within a week suggests the lead is actively researching solutions, not just browsing. † 第7天行为是高价值行为，表示“意图加速”——一周内重复互动说明潜在客户正在主动研究解决方案。 2) **AI keeps in C Pool because score (34) is well below the 60 threshold.** High engagement raises trend but not enough to cross the upgrade line. Nurturing must continue until cumulative behavior proves sustained readiness. † AI保留在C池，因为当前分数34远低于升级阈值60。单日高价值行为虽提升趋势，但尚未达到充分条件。 3) **Triggered actions: send a case study on “training ROI” via email + schedule a low-touch sales call (BDR) for next week.** Keep it educational, not pushy. † 触发动作：发送题为“培训投资回报率”的案例研究报告邮件，并由BDR安排下周的低介入销售通话，保持教育性而非施压。 4) **This supports a 100-unit pipeline by converting passive research into active demo requests.** The case study and BDR call directly address likely pain points (training scale & cost), increasing the chance of a qualification meeting. † 支持100单元商机转化：案例研究与BDR通话直接回应潜在痛点在培训规模与成本，提升资格会议可能性。
