Win probabilities are assembled from several data sources of varying reliability. The Odds Quality score (0–100) indicates how much direct market data supports each team's estimates.
Higher scores mean the probability comes from direct sportsbook odds—like head-to-head moneylines or complete futures pools—which are straightforward to convert into probabilities.
Lower scores mean the estimate relies on indirect methods: incomplete odds pools, imputation from other rounds, or historical seed averages. This can happen when a team is missing from the odds entirely (e.g. due to regional betting restrictions).
Each team's score is the average across all rounds. The overall score is a weighted average across all teams.
