Games back
To calculate games back (GB) of a baseball team, just use the following formula:
Games back = (Difference in wins + Difference in losses) / 2
The formula above applies only to a team and it is used to determine the number of GB a team is from the
first place.
The difference in wins is a always positive number, so is the difference in losses
Therefore, when computing the GB, always do
bigger number 
smaller number so that the difference is always positive
Example:
Use the following table to compute the GB between the first place and the other teams
Team

Number of wins

Number of losses

GB

First place team

34

22

N/A

Second place team

30

24

3

Third place team

28

26

5

Fourth place team

24

28

8

GB between first place and second place = (Difference in wins + Difference in losses) / 2
Differences in wins = 34  30 = 4
Differences in losses = 24  22 = 2
GB between first place and second place = (4 + 2) / 2
GB between first place and second place = (6) / 2
GB between first place and second place = 3
GB between First place and third place = (Difference in wins + Difference in losses) / 2
Differences in wins = 34  28 = 6
Differences in losses = 26  22 = 4
GB between first place and third place = (6 + 4) / 2
GB between first place and second place = (10) / 2
GB between first place and second place = 5
GB between first place and fourth place = (Difference in wins + Difference in losses) / 2
Differences in wins = 34  24 = 10
Differences in losses = 28  22 = 6
GB between first place and third place = (10 + 6) / 2
GB between first place and second place = (16) / 2
GB between first place and second place = 8
Note that the formula above can be used to calculate the games back for other sports. It does not have to be baseball only.
