[edit] Calculation accuracy
On how to calculate GAA, the first method was too far off and would be far from accurate. It's only be accurate if the goalie let in the same amount of goals in the same amount of mins. Ex: 2 GA x 60 divided by 180 = 2 GAA. Right way: Minutes: 3024 divided by 60 = 50.4 GA: 120 divided by 50.4 = 2.38. So does anyone agree with with me on this?

Well, your math is wrong on the first example: 2 GA x 60 = 120, divide by 180 you get a GAA of 0.67. which would be correct for 2 goals allowed in 3 complete game (or equivalent). Your second example is calculated correctly, however it describes a different scenario: 120 goals allowed in 3024 total minutes. Calculated in the same way as the first example: 120 GA x 60 = 7200 divided by 3024 = 2.38.
Another note: to calculate GAA for football (soccer) you need to use 90 instead of 60 since of course a football game is 90 minutes. Wschart 12:57, 11 April 2007 (UTC)
