Measured from the 1 manifests the account has read, since it gained Half-Life 2: Year Long Alarm on 30 Sep 2026. Install bytes are the uncompressed file sizes of the default install (Windows, base game, English); depots behind DLC or keys, other languages and low-violence variants are counted apart and shown under every depot. Download and fresh-download bytes are compressed chunk lengths; the two are never added together. Efficiency is a patch’s download divided by the bytes it rewrote on disk.
