Prices are implied probability derived from each venue's live quote (exchange price or American odds with vig). Best marks the single highest-payout price across every venue for that entrant. Edge = sportsbook-consensus probability minus exchange probability, in percentage points — a positive edge means sportsbooks price that outcome higher than the exchange does. Stale flags any quote observed more than 48 hours ago.
