- **Day 7 repeated high-value engagement signals active buying intent.** Multiple visits, video watches, or repeat interactions in one day show the lead is researching seriously, not just browsing once. **第7天多次高价值互动说明客户有明确采购意向。** 一天内反复访问、看视频或多次互动，代表其正在认真评估，而不是随便看看。 - **AI keeps the lead in C Pool because history still dominates.** Days 1–6 score is 0 and Day 7 predicted score is 0, so the cumulative score does not cross the C→B threshold of 60; one strong day is not enough for upgrade. **AI仍将其留在C池，是因为历史行为权重更高。** 前6天分数为0，第7天预测分也为0，累计分未达到C升B的60分门槛；单日强互动不足以直接升级。 - **However, Day 7 should trigger a high-priority nurture task, not a pool upgrade.** The system should flag the account, notify sales, and schedule follow-up within 24 hours. **但第7天应触发高优先级培育任务，而不是直接升级池。** 系统应标记该客户、提醒销售，并在24小时内安排跟进。 - **Recommended triggered actions: send a tailored B2B training proposal, offer a short discovery call, and share a 100-unit distribution/enterprise package overview.** This tests budget, scale, and decision timeline without overcommitting sales resources. **建议触发动作：发送定制化B2B培训方案、安排简短需求沟通、提供100套分销/企业包概览。** 这可在不过度投入销售资源的前提下，验证预算、规模和决策时间表。 - **Business outcome: this protects pipeline quality while accelerating a likely 100-unit distribution inquiry.** If the lead responds to the proposal or call, score can rise quickly and upgrade to B, improving conversion efficiency and deal size. **业务结果：既保护管道质量，又加速可能达成的100套分销询盘。** 若客户对方案或沟通有回应，分数可快速上升并升级到B池，从而提升转化效率和客单规模。
