Case contract

Winning accumulator bonus. Every leg price multiplies the accumulator. Legs priced at 1.20 or more qualify; the bonus percentage by qualifying count is {3: 5, 4: 10, 5: 15, 6: 20, 7: 25} with 7 or more paying 25 and fewer than 3 paying 0. The bonus is applied to the profit only: return = stake + profit * (100 + pct) / 100, rounded down. Return [qualifying legs, bonus pct, return cents].

Why this case matters

Acca promotions depend on minimum-odds qualification and apply the bonus to winnings.
