Badminton predictions: format, model & how to follow
Badminton is DeuceLab's second sport. It is tournament-based rather than a round-the-clock firehose, so the model is built around real BWF and international singles draws.
What we cover
We track singles across the international badminton calendar — World Tour stops, Opens and internationals — and aggregate them into one rating pool. Doubles are deliberately excluded: a per-player rating only makes sense for singles, so any match with a paired name (for example "Chen/Corbett") is filtered out.
Because the field rotates between tournaments, the player pool is broad and fast-changing. That keeps the rankings lively but means some players appear only a handful of times.
The model
Each player carries an Elo rating, exactly as in our table tennis model. The rating gap gives a match win probability, which we then invert into a per-game probability for best-of-three scoring and calibrate against past results.
Measured walk-forward, the badminton model grades out as Good — around 62% pick accuracy with a Brier score near 0.242. Honest, useful, and verifiable on the calibration chart.
Live and in-play
Once a match is under way we compute a live win probability from the current game and point score — best-of-three, games to 21 — updated continuously. You will find it on the Live page under the Badminton tab.
The honest part
We tested the badminton model against real closing odds: the market is sharper (Brier 0.19 versus our 0.24). As with table tennis, there is no reliable edge. DeuceLab is a transparent model and a second opinion, not a profit system.
