On the myopl.net platform, the “OPL rating” is the core metric, while “league ranking” refers to a player’s position within a specific league based on various standard league metrics. They are related but distinct: the OPL rating is the underlying universal skill algorithm, while league rankings use a combination of factors for league standings.
OPL Rating Algorithm
The OPL Rating is a single, universal skill measurement that applies to every player on the platform, regardless of age, gender, or location. It is data-driven and real-time.
- Calculation Factors: It incorporates match performance, the strength (rating) of opponents, game scores, volatility, and rating deviation.
- Purpose: To provide an accurate, objective, and comparable measure of a player’s true skill level (on a 2.0 to 8.0 scale) across all open play games logged on the platform.
- Dynamic Adjustments: The algorithm is designed for rapid convergence, adjusting ratings quickly to reflect significant changes in performance, such as upsets or sudden skill improvements.
League Ranking Algorithm (Standings)
“League Ranking” or “League Standings” refers to a player’s position within a specific, localized league that a user has joined or created on myopl.net. Unlike the universal OPL rating, league rankings are typically determined using a more traditional hierarchy of factors, often focused on wins and losses within that specific league.
- Primary Factor: The main metric is usually the overall win/loss record within the specific league.
- Tie-Breakers: When players have the same win/loss record, tie-breaking criteria are used to determine their final rank in the standings. These criteria commonly include:
- Head-to-head record against tied opponents.
- Total point differential (points won minus points lost).
- Total points scored.
League Seeding Algorithm (Seed)
“League Seeding” is a League specific skill measurement for determining a players rankings within each league. This allows for more efficient tournament organization and a better match pairing system. The system helps in creating fairer competition and provides visual feedback on improvement and clear goals for skill development.
- Primary Factor: The main metric is usually the overall win/loss record within the specific league.
- Tie-Breakers: When players have the same win/loss record, tie-breaking criteria are used to determine their final rank in the standings. These criteria commonly include:
- Head-to-head record against tied opponents.
- Total point differential (points won minus points lost).
- Total points scored.
Key Distinction
In short:
- The OPL Rating is a player’s universal skill measurement calculated by a sophisticated ELO-based algorithm that updates with every match logged.
- The League Ranking is a player’s position on a specific league table determined primarily by traditional league metrics like win/loss record and tie-breakers.
- League Seeding is a player’s position on a specific league table League determined primarily by analyzing a player’s existing ratings while comparing expected scores to actual scores, and then applying a rating adjustment that uses a scaling factor to control the maximum potential change in a player’s rating from a single game.
A player with a high OPL rating might be ranked lower in a specific league’s standings if they have played fewer games in that league or had some early losses, while a player with a lower OPL rating might top the league if they consistently win their league games against similar-skilled opponents.
