All GLS stocks forecast the Global Lifetime Sales of a game--meaning the total unit sales of the game's lifetime. A forecast of the subscriber-base "in lifetime" should be equal to the GLS if each subscriber is required to buy the game.
A forecast of the active subscriber-base would have to be associated with a particular point in time, as the subscriber-base goes up and down on a day to day basis. It would not be possible to have a GLS stock targeting "active subscribers." GLS stocks do not represent the present state of sales/subscribers, but rather the ultimate future state in which all sales have been made.
