评分推导

VPN Cat

在 Default (evidence-weighted) 权重方案下，就我们持有证据的那 44% 的方法论而言，VPN Cat 得到 5.2 分，可证明介于 2.30（每一个未测量维度都处于最差状态）与 7.55（每一个都处于其已公布的最高值）之间。

5.2证据覆盖率 44%（不是第二个评分）

可证明介于 2.30 与 7.55 之间

权重方案：Default (evidence-weighted)。Weights are allocated toward what this site independently verifies. Speed and streaming are vendor-claimed rather than measured here, so they carry roughly half the weight the industry standard assigns them; that weight moves to privacy, transparency and server authenticity, all of which are checked against primary documents or our own probe network.

如何解读推导

实测
这个数字由我们自己产出，并且可以复现。
有据可查
读取自第一手文档：隐私政策、审计报告或源代码。
厂商声称
由提供商单方面声明。我们尚未独立核实，因此评分相应设有上限。
无证据
我们没有找到任何可供评分的依据。该维度会被排除在加权平均之外，而非计为零分。

✓ 表示我们检查过、且没有发现任何问题的一条规则，对于一家无日志提供商而言，这正是重点所在，而不是消息缺失。“未披露”一行是我们评了分并附上引用的一个负面项；“未评估”一行是我们自己的空缺，它会降低覆盖率，但不会让该提供商付出任何代价。这里的每一个评分，都是对 已公开的证据 的一次 已公开的公式 读取。
