Pythagorean Records

As we have in past seasons, throughout the year we will track how the teams are doing in relation to their pythagorean expected records. Pythagorean winning percentage is an estimate of a team's winning percentage based on their runs scored and runs allowed. It can tell you whether the teams are a bit lucky or unlucky. It is calculated with this formula: (Runs Scored)^1.83/((Runs Scored)^1.83 + (Runs Allowed)^1.83). It's still early in the season, but so far everyone is about where they should be.

Team, actual wins, actual losses, runs scored, runs allowed, pythagorean wins, pythagorean losses, difference between actual and pythagorean.

  1. Have always thought this one (computation) was really spooky. Thanks for putting it together, Doug.
