Things worth knowing about acca boost
- The boost applies to returns, not to each price
- A 50% acca boost doesn't lengthen your selections — it adds a percentage to what the multiple pays if every leg lands. One losing leg and the boost is worth nothing.
- Minimum legs and minimum odds both matter
- Most boosts need four or five legs before they start, and set a minimum price per leg to stop people stacking odds-on shots. Both are in the terms below.
- There's nearly always a cap
- The headline percentage is the maximum, and the cash value of the boost is usually capped too. A big percentage on a small cap is worth less than it looks.
