If a pitcher goes 8-4, meaning 8 wins, 4 losses, add the two

together which would be 12, and divide the wins, in this case 8 by

the total games he had a decision, 12, and the answer would be

represented as .666.

### How do you calculate RPI in college basketball?

The RPI calculates 3 percentages: team's winning percentage,
opponents' winning percentage, and opponents' opponents' winning
percentage.
To calculate the team's winning percentage:
Wins: home wins * 0.6 + road wins * 1.4 + neutral wins
Losses: road losses * 0.6 + home losses * 1.4 + neutral
losses
Then calculate your winning percentage using wins / (wins +
losses). This % is weighted 25%.
Opponents' winning percentage is calculated using the exact same
method as shown above, however exclude all games played with the
team (that's RPI is being calculated). This % is then weighted
50%.
Opponents' opponents' winning percentage is calculated by the
average of the team's oppenents adjusted winning %. Simply, use the
same method above for calculating the oppenents' winning
percentage, however using it for the opponents' opponent and
excluding only the team once again (not the opponent). Repeat this
method for each team, and average the winning percentage. This % is
then weighted 25%.
Finally, add up all scaled RPI points, and get a total RPI
ranking.
