- The proposed ladder combines Glicko-2, margin of victory, and a visible reliability percentage.
Field notes
The proposed system separates a player's position from its confidence in that position, displaying rating deviation as a reliability percentage. Its example card lists Emerald II Singles at 1642, after 34 matches, with 82% reliability. The homepage also defines promotion thresholds, including 1500–1700 for Emerald and 1700–1900 for Platinum. Match entry and live rankings are not visible because the project is still pre-launch.
