The assumption of goals against average is that the average game is 60 minutes.
So if a goalie allows 3 goals and is pulled for the last 1.5 minutes then they actually played 58.5 minutes.
That would mean that their GAA for the game would be slightly over 3.
It would precisely be:
3 goals * 60 minutes (average game)/ 58.5 minutes (time actually played)
So in the above circumstance the GAA would actually be:
Its really not that complicated when you understand that a goalie can play less than, or more than a full game in the course of a game.
Another example would be a goalie that gives up 4 goals in the first and gets pulled after 20 minutes.
GAA = 4 * 60/20 = 12
