The Rating Percentage Index is a quantity used to rank sports teams based upon a team's wins and losses and its strength of schedule. In its current formulation, the index comprises a team's winning percentage (25%), its opponents' winning percentage (50%), and the winning percentage of those opponents' opponents (25%). The opponents' winning percentage and the winning percentage of those opponents' opponents both comprise the strength of schedule (SOS). Thus, the SOS accounts for 75% of the RPI calculation and is 2/3 its opponents' winning percentage and 1/3 times its opponents' opponents' winning percentage.

the yankees Was the question "what BASEBALL team", or just what team? If the latter, it is definitely NOT the Yankees: At a glance, the Boston Celtics (without actually looking at what games were played in 1979 and the first half of the 1989-90 season) had a winning percentage of .722 from the 1979-80 season to the 1988-89 season. The Yankees during the 80s had a winning percentage of .547. Once again, without researching games during 1979 and the latter half of 1989, the Edmonton Oilers winning percentage was .623 from 1979-80 to 1988-89. The San Francisco 49ers had a winning percentage of .688 during the 80s. Wishing thinking on the part of the obvious Yankees fan who provided the previous answer. It's possible the Yankees were the most successful BASEBALL team, but they certainly did not have the highest winning percentage of all sports. For that matter, the question might include teams not in North America, which further complicates the answer.
