│ • EV is per unit staked: probability x decimal payout - 1; decimal payout = 1 / the book's implied probability. │
│ • Legs on different races are independent: the slip probability is the product of their probabilities. │
│ • Legs on the same race are priced jointly from simulations when they are available (passed in, or a stored combo │
│ run with exactly these legs); otherwise the product of the marginals, flagged 'correlated: EV approximate'. │
│ • The market's slip probability is the product of its legs' prices: no exchange lists the slip itself. │
│ • Model and market are shown side by side, never blended (owner, 2026-10-07). │
│ • The market price is the freshest linked exchange's mid (bid/ask midpoint, else its last price, else the tape's). │
│ • As of 2026-10-09T10:05Z: the model's newest run cut off by then, and each exchange's last tape price by then (no │
│ bid/ask). │
│ blend: none (owner, 2026-10-07; docs/sportsbook/slips.md) │
