What is Glicko-2?
Glicko-2 is a skill rating system (an evolution of ELO) that ranks competitors from their match results. As bots fight, their ratings update in a way that factors in the skill and rating-certainty of each competitor. KOdex computes it chronologically from NHRL's datasets and updates in real-time during events, so KOdex always reflects the NHRL competitive roster as fights happen.
Rating
The skill estimate. Movement is weighted by how surprising a result is given each competitor's prior rating.
RD (rating deviation)
How certain we are of that rating. A high RD means less certainty. RD shrinks as a bot develops history and we learn where it really stands.
Volatility
How erratic recent results have been. Streaky, up-and-down performances read as more volatile than steady, predictable ones.
Rating certainty is earned.
Every rating on KOdex carries its RD (rating deviation), so a bot with sparse fight history reads as provisional versus data-rich competitors. A settled bot has low RD, a fresh one has high RD, and that classification travels with the number wherever it appears.
The color and the readout tell you how much to trust a placement at a glance, without having to guess at how many fights are behind it.
- Settled1842
Low RD, a seasoned competitor
- Developing1605
Medium RD, only few events in
- Provisional1490
High RD, very new or very inactive
What makes KOdex different?
NHRL-only scope
A bot's rating here reflects only NHRL competitions where builders are trying hard to win, with no other tournaments blended in. Ratings stay meaningful because they measure one arena.
Real-time during events
Ratings and records update live as fights happen. No waiting for results to be aggregated after the event wraps, you watch the standings move in the moment.
Data-driven awards
Bots earn badges for achievements and milestones, from podiums to statistical anomalies. Each badge links to every bot that holds it, so you can explore the roster through its highlights.
