- **Day 7 callback request = explicit buying intent.** A prospect asking to speak with the success team signals active evaluation, not passive browsing — the strongest single signal in B2B nurturing. - 第7天主动申请回电，等于明确表达采购意向。愿意与成功团队直接沟通，说明客户在认真评估，而非随意浏览——这是B2B培育中最强的单一信号。 - **Score 14 vs. threshold 60: high-value behavior, but not enough cumulative evidence.** The AI weights breadth and depth of engagement (repeat visits, video completion, multiple stakeholders); one strong action lifts the score but stays in C Pool — correct discipline, avoiding premature sales cost. - 14分离60分门槛仍有差距：行为价值高，但累计证据不足。AI综合评估互动广度与深度（多次访问、视频完播、多角色参与），单次强行为会加分但仍留在C池——这是合理克制，避免过早投入销售成本。 - **Trigger precise, low-cost nurturing.** Route the callback to the success team within 24h; send a tailored 100-unit distribution proposal plus a short case study; log a sales follow-up task and set a re-score checkpoint at Day 10–14. - 触发精准、低成本的培育动作：24小时内将回电转交成功团队；发送定制的100套分销方案及简短案例；创建销售跟进任务，并在第10–14天设置重新评分节点。 - **Path to the 100-unit inquiry:** callback → needs validation → proposal →demo/quote. Each completed step compounds the score; crossing 60 upgrades C → B and activates proposal/follow-up automation, accelerating pipeline velocity. - 通往100套询盘的路径：回电→需求确认→方案→演示/报价。每完成一步都会累加评分；突破60分即从C升至B，自动触发提案与跟进任务，加快商机流转。 - **Business outcome:** disciplined scoring protects sales capacity while the callback keeps a high-potential account warm — improving conversion rate and deal size without inflating pipeline cost. - 业务结果：严格的评分机制保护销售产能，同时回电让高潜客户保持热度——在不增加管道成本的前提下提升转化率与客单价。
