**1) Why "Requested callback" is high-value** - It is an explicit, self-initiated buying signal — the lead asks for human contact, not just content consumption. - 主动要求回电是明确的购买信号，而非被动浏览内容。 - It shortens the sales cycle by removing the qualification guesswork. - 省去资格判断环节，直接加快销售周期。 **2) Why the AI upgrades C → B** - Cumulative engagement (50) plus a high-intent action pushes predicted score to 61, crossing the C→B threshold of 60. - 累计互动加上高意向行为，使预测分达到61，越过C→B阈值60。 - Behavior → score → pool logic: intent weighting on callback requests outweighs passive views. - 行为→评分→分层逻辑：回电请求的意向权重高于被动浏览。 **3) Precise nurturing actions to trigger** - Send a tailored B2B proposal and route to a sales follow-up task within 24h. - 发送定制化B2B方案，并在24小时内触发销售跟进任务。 - Assign success-team callback + schedule discovery call; log in CRM as B-pool playbook. - 安排成功团队回电+预约需求挖掘通话，按B池剧本记录CRM。 **4) Path to a 100-unit distribution inquiry** - B-pool treatment (proposal + sales touch) nurtures toward A (threshold 120), where volume deals like 100 units convert. - B池的提案+销售触达推动升级至A池（阈值120），更易转化大单。 - Higher score = higher deal potential and better pipeline quality, improving conversion and sales efficiency. - 评分越高，成交潜力与商机质量越高，提升转化率与销售效率。
