For example, in 2021, a single was worth .879 runs, while a home run was worth 2.007 runs in the formula for wOBA.

In most cases shown in Table 1, the Pythagorean prediction of WP is very close to the actual winning proportion, and by extension, the Pythagorean prediction of team wins is usually very close (perhaps within three) to actual team wins. The sabermetrician Bill James created the Pythagorean expectation formula, and it is a way that you can predict the number of wins or losses you can expect a baseball team to experience. [3] The updated formula therefore reads as follows: The most widely known is the Pythagenport formula[4] developed by Clay Davenport of Baseball Prospectus: He concluded that the exponent should be calculated from a given team based on the team's runs scored (R), runs allowed (RA), and games (G).

It would be expected that differences in performance in games decided by more than one run also could account for some of the differences noted between actual and Pythagorean records.

These included 19 seasons in which the actual winner was also the Pythagorean winner, five seasons with a tie for the Pythagorean pennant, and 28 seasons (54 percent) in which the Pythagorean winner differed from the actual winner. In addition, to further filter out the distortions of luck, Sabermetricians can also calculate a team's expected runs scored and allowed via a runs created-type equation (the most accurate at the team level being Base Runs).
