**1) Why Day 7 callback request = high value** - Requesting a callback is an explicit buying signal — it shifts from passive browsing to active seller contact. - 请求回电属于明确购买信号，代表客户从“被动浏览”转向“主动联系销售”。 **2) Why the lead stays in C Pool** - Predicted score = 2 vs upgrade threshold = 60 → strong intent, but weak total engagement depth. - 预测分仅 2，远低于升级阈值 60，说明意向虽强，但整体互动深度不足。 **3) Precise nurturing actions to trigger** - Create a priority sales follow-up task within 24h; assign to senior rep or success team. - Send a tailored B2B training proposal + enterprise distribution/inquiry deck. - Log call outcome and set a next-step reminder to accelerate score accumulation. - 24 小时内创建优先跟进任务并分配给资深销售/成功团队；发送定制化企业培训方案及分销询盘资料；记录通话结果并设置下一步提醒，以加速分数累积。 **4) How this supports a 100-unit distribution inquiry** - Callback conversation surfaces budget, scale, and rollout timing → qualifies the 100-unit opportunity. - Proposal can be positioned as bulk distribution / multi-seat enterprise deal, not single course purchase. - 回电沟通可挖掘预算、规模与上线时间，从而验证 100 单位分销机会；方案应按批量分销/多席位企业采购来定位，而非单次课程购买。 **Logic chain:** behavior → score rises → no pool upgrade yet → task + proposal triggered → sales qualification → 100-unit distribution deal potential. **逻辑链：** 行为 → 分数提升 → 暂未升级池 → 触发任务与提案 → 销售资格验证 → 100 单位分销成交潜力。
