  Brave shows how many ads and trackers it has blocked, as well as a number that's labeled Time Saved. How that is calculated I haven't the foggiest, but it must be related to download size.

        You know, I think you're right. The formula from the PR that implemented "Est. Time Saved" appears to be (trackers + ads blocked) * 50ms https://github.com/brave/browser-android-tabs/pull/331/files#diff-78893a1dc301286f35272e54fa39e4cbR477 https://github.com/brave/browser-android-tabs/pull/331/files...

  You can get that information from, e.g., a Squid proxy (the daily/weekly/monthly reports). Even for non-cached content.
