What Is Rule 4?
Rule 4 is a deduction applied to winning bets when a horse is withdrawn after bets have already been placed.
When a runner is removed from a race, the overall competitiveness of the race changes. Rule 4 adjusts returns to reflect this.
How Is the Deduction Calculated?
The deduction amount depends on the withdrawn horse’s odds at the time it was removed.
The shorter the withdrawn horse’s odds, the larger the deduction may be.
Rule 4 only applies to winning bets and is displayed in the market once confirmed.
