Default (evidence-weighted) の加重において、Proton VPN は証拠を保有する方法論の 79% に基づき 8.7 を獲得しています、6.88（未計測の評価項目がすべて最悪の場合）から 8.88（すべてが公開されている最大値の場合）の間にあることが証明可能です。
8.7証拠カバー率 79%（別のスコアではありません）
6.88 から 8.88 の間にあることが証明可能
加重: 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 6.885 は値の列を合算したものです。上限 8.880 は、代わりに各未採点の評価項目をその上限値で加算します。採点された 79% にわたって下限を再正規化すると 8.72 となり、これを上限以下に抑えて 8.7 を公開しています。
