About
Flat Track Stats is a comprehensive statistics and analytics platform dedicated entirely to flat track roller derby. It aggregates bout results from leagues around the world—primarily WFTDA-affiliated teams—and transforms raw scores into meaningful data: team ratings, global rankings, week-over-week movement, and head-to-head historical records. At its core, the platform uses a rating algorithm (similar in spirit to Elo-style systems) to assign each team a numeric rating. These ratings power a Predictor tool that calculates win probabilities and expected score ratios before each bout. After results come in, the site highlights biggest upsets, closest predictions, and biggest movers so fans can quickly understand how each week shifted the competitive landscape. Key sections include a weekly bout dashboard with 'Bouts to Watch' and 'Closest Bouts' highlights, a full Tournament tracker, time-travel navigation to explore any historical week, and a Labs section for experimental features. Teams and organizers can log in to submit schedules, scores, and detailed stats directly to the platform. Flat Track Stats is ideal for roller derby fans wanting real-time global standings, team staff analyzing competitive positioning, league administrators managing records, and sports analysts studying the mechanics of derby matchups. The site covers multiple regional and international divisions, making it the single most data-rich resource in the flat track roller derby ecosystem.

Frequently Asked Questions
What is Flat Track Stats?
Flat Track Stats is a free, web-based platform that tracks bout results, team ratings, and global rankings for flat track roller derby, primarily covering WFTDA-affiliated leagues worldwide.
How are team ratings and rankings calculated?
Ratings are computed using an algorithmic system based on bout outcomes, score ratios, and opponent strength (Degree of Strength). Each result causes rating adjustments for both teams, which in turn updates the global ranking order.
What is the Predictor feature?
The Predictor uses current team ratings to estimate the win probability for each team in an upcoming bout, along with an expected score ratio. After the bout, it shows how closely the actual result matched the prediction.
How do I submit scores or stats?
Authorized league organizers and team staff can log in to the platform and use the Submit section to enter schedules, final scores, and bout statistics for their leagues.
Does Flat Track Stats cover divisions beyond WFTDA?
Yes. While the most prominent rankings focus on WFTDA-affiliated teams, the platform also tracks other regional and divisional competitions, as reflected by the multiple regional filters on the weekly bout dashboard.
