If you are a regular follower of an Australian horse racing, you might have noticed that the odds you saw while placing a bet may change post scratching of a horse. This is exactly where horse racing deductions comes into play.
At initial phase, deductions might seem confusing, but the basic idea is upfront, they adjust fixed odds when a runner is withdrawn from a race. A clear understanding of their working can assist punters in knowing what to expect when a late scratching puts an impact on the market.
What Is a Deduction in Horse Racing?
A deduction is the reduction applicable for the fixed odds of the remaining runners whenever a horse is scratched from a race. Why it is applied? After withdrawal of a horse, the chances of other runners winning efficiently enhances. If in case the scratched horse was well-fancied, its removal can have a substantial impact on the market.
Like for instance, the price of a horse is $1.10 and is scratched. The remaining runners now have a good chance of winning. Instead of allowing punters to retain the original price, bookmakers make adjustment of the odds through a reduction. The bet on the scratched runner is then refunded, while applied bets on the other runners are deducted.
The amount deducted relies highly on the price of the scratched horse. In general, the shorter the odds of the horse, the bigger is the deduction.
How Are Horse Racing Deductions Calculated?
Bookmakers make use of deduction tables for determining the right percentage. While the precise figures might vary in between the bookmakers, the principle remains the same. Like for example, if in case the scratched runner outcome is 40% deduction and you had supported another horse at $5, the adjustable odds is calculated through multiplication of $5 with 0.60. This results in adjusted odds of $3.00.
This is the reason why checking the deduction percentage is vital while reviewing a bet post a scratching. A long priced runner, might have very less or no effect on the prices of the other horses. The larger the supposed influence of the scratched runner on the market, the bigger is the deduction.
When Do Deductions Apply?
Deductions is mainly applied to fixed odd bets on final field markets. These are the markets where final declaration of the runners has been done and there is availability of the information such as barrier positions and jockeys.
In general, they are applied to the tote bets. With tote betting, redistribution of complete betting pool is done post scratching, so that the dividend are adjusted accordingly.
It is also vital to understand that the difference between final field and All in or futures markets. Deductions normally does not apply to all in Bets as these markets are provided before the final field is known. But there is a vital trade off, if the horse you supported do not takes its place ultimately, your bet loses instead of being refunded.
