Alliance Leagues Adopt One Scoring System
January 15, 2021 — The Alliance Fastpitch and all six Member Leagues are excited to announce the adoption of one scoring system across all Leagues. Following our Winter Meetings, all Leagues agreed to adopt one scoring system to maintain consistency across the country and to simplify for our teams. The Alliance Rating System will serve as the points and scoring system for all teams playing in one of our Member Leagues. The Alliance Fastpitch has worked directly with AthletesGoLive to implement the Alliance Rating System.
The Alliance Rating System is based off the popular Elo Rating formula, which is used by FIFA, Sagarin (NFL, MLB, NBA, NHL, College Sports), and 538.com (NFL, MLB, NBA, NHL). Our system is able to predict win probabilities, is internally consistent, awards performance, and is a simple and easy formula to calculate.
The Alliance Rating System will impact all League games moving forward. League Commissioners will identify all events within their League where teams can earn points. Those events will have an AthletesGoLive (AGL) event number so our system can recognize it is a points event. In order for your points to count, teams must utilize their AGL Team Account (which a free account with AthletesGoLive) to score the game. Following these League events, the scores will be automatically calculated into your team’s overall point value.
All teams will start off with an initial rating of 1600. Teams exchange points based on the outcome of games.
- A team that does better than expected improves its rating
- A team that does worse than expected lowers its rating
Stronger teams must beat weaker teams consistently to maintain or increase their rating. Weaker teams can play stronger teams without having to win a lot of games and still improve their rating. Teams have an incentive to play STRONG teams and will be rewarded for their performance.
The following leagues have already integrated games from the Fall.

We will be tracking non-Alliance teams as well throughout the season as long as those teams are registered in AthletesGoLive and their AGL Team ID is entered correctly when scoring the game. If at any time during the season, those non-alliance teams register for the alliance, we will transfer their records and ratings into our leaderboards and their rating will be based on the games we’ve tracked them in.
The Alliance Power Points (APP) will be awarded to League teams for inter-league play against teams from another Member League. Points will be awarded based on the following:
|Traveling Team Wins||3||Neutral Ground Win||3|
|Traveling Team Tie||2||Neutral Ground Tie||2|
|Traveling Team Loss||1||Neutral Ground Loss||1|
|Local Team Wins||2|
|Local Team Tie||1|
