The SteamPeaks account does not own Snowplow Therapy Demo, so no manifest of it has been read and there is no size to measure. The Depots section shows the sizes Steam reports for each depot; the history starts the day a free licence or a key adds the game to the account.
The SteamPeaks account does not own Snowplow Therapy Demo, so none of its files are in the index and nothing can be compared until a licence adds it. 15,344 games are indexed today.
