How does the rpi work?

Answer 1

RPI is a calculation that takes into account both a team's winning percentage and its strength of schedule. RPI is calculated out of 1. The formula is a team's winning percentage times .25 + the team's opponents' winning percentage times .5 + the opponents' opponents' winning percentage times .25. Additionally, when calculating winning percentages for NCAA Basketball, a win at home counts as 0.6, a road win is 1.4, and a win on a neutral court is 1. For example, let's say Ohio State plays 3 games, 2 at home and 1 away, and wins all 3. Additionally, assume those opponents had a combined winning percentage of .600 and the opponents' opponents had a winning percentage of .450. Ohio State's RPI would be: (([(2 x 0.6) + (1 x 1.4)]/3) x .25) + (.600 x .5) + (.450 x .25) = .6292
