評分推導

VPN Cat

在 Default (evidence-weighted) 加權下，VPN Cat 在我們握有佐證的 44% 評分方法上取得 5.2，可證明介於 2.30（每一項未實測面向都取最差值）與 7.55（每一項都取其公開最高值）之間。

5.2證據覆蓋率 44%（不是第二個評分）

可證明介於 2.30 與 7.55 之間

加權方式：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.

下限 2.302 是數值欄的加總；上限 7.552 則改以各未評分面向的上限值計入。將下限在已評分的 44% 上重新正規化後得到 5.23，並壓在上限或其以下，最終公布為 5.2。

如何解讀推導

實測: 這個數字是我們自己產出的，並且可以重現。
有文件佐證: 直接讀自第一手文件：隱私權政策、稽核報告，或原始碼。
供應商自述: 由供應商自行宣稱。我們並未獨立驗證，評分也因此設有上限。
無佐證: 我們找不到任何可供評分的依據。此面向會被排除在加權平均之外，而非計為零分。

「✓」代表我們查核過、且未發現任何問題的規則，對於一家不記錄日誌的供應商而言，這正是重點，而非沒有消息。「未揭露」的項目是我們已評分並引用的負面事實；「未評估」的項目則是我們自己的缺口，它會降低涵蓋率，但不會讓供應商付出任何代價。此處的每一項評分，都是以已公開公式對已公開佐證的一次解讀。
