Note to editors. Rule 4 is a general rule of betting which relates to the reduction of winnings when a horse you have backed wins or is placed. They are made when a horse is withdrawn from a race because it becomes easier for the other runners to win.
Rule 4 deducts a set value in pence out of every pound in winning bets, with the size of the deduction determined by the price – either early or show – of the non-runner. The level of deductions ranges from 90p in the pound at 1-9 or shorter to 5p in the pound at odds of 10-1 to 14-1.
So to calculate how much a rule 4 costs you all you need to do is change 'pence' to percent and deduct that from your profit. As an example, a 5p rule 4 deduction on a £100 stake on a 10/1 winner will reduce your profit by 5%.
Westgard Rule R. 4s
The R4s rule applies to controls within a run. If two controls exceed 4SD, that is, if one control exceeds +2SD and the other control (or another control, if more than 2 controls are tested) exceeds -2SD, the run should be rejected.
SUPERFECTA– You bet that four horses will finish, first, second, third, and fourth in an exact order. As with exactas and trifectas, you can box a superfecta at an additional cost. The minimum bet is often 10-cents, which makes it more appealing to many people.
With a trifecta, you will need to include three horses in your selection to finish in first, second, and third position, in that exact order. A superfecta bet is considered the most difficult, as you will need to include four horses in your selection to finish in the top 4 positions, in the exact order as well.
For example, choosing four horses in your Combination Trifecta would mean your bet would include 24 bets.
If an even money shot is withdrawn immediately prior to the race after a punter has bet on another horse, bookmakers will take a 45 pence rule 4. This means that for every £1 you have staked, 45 pence will be taken away.
Rule 4 deductions are normally made in cases where you have taken a price on your horse. Rule 4 deductions can be made from the Starting Price (SP) of a horse when a horse is withdrawn just before the race and there is no time to create a new a market.
After a race becomes Non-Runner No Bet, any Future Racing bets placed on the Win or Each-Way market will be refunded if your selection does not run.
You may not be familiar with a Rule 4, or R4 - that is until it has been applied to your bet and you receive a lower payout amount than you were expecting. Rule 4 is an industry wide deduction rule created for when there are non-runners in a horse/greyhound race after the final declarations have been made.
Markets may be subject to a Rule 4 (Deductions). If the specified meeting is abandoned before all races have been run or if one or more races is declared void, then all bets will be void, unless settlement of bets is already determined.
The winnings you would receive from a bet is calculated by multiplying your stake by the odds.
Scratches. If a horse is scratched, all Win/Place/Show wagers placed via the racing interface will be refunded. (This does not apply to 'Odds to Win' bets placed via the sportsbook. On those bets a scratch counts as a loss).
Rule 4 tells us that vessels operating under any and all conditions of visibility are required to follow Rules 5 through 10. In other words, these Rules apply all of the time.
In the event of a horse being withdrawn, not under starter's orders, stakes on that selection will be returned. Bets for the remaining horses in the race will be subject to a deduction in accordance with Tattersall's Rule 4 based on the win price of the withdrawn horse(s) at the time of withdrawal.
If a horse comes under starters orders but doesn't race, then any bets on this horse are settled as losers. This applies to stall starts (horse refuses to leave the starting stalls) or tape starts (where the tape is lifted, but the horse doesn't go with the field).
What is Rule 4? Rule 4 covers the situation where a horse is withdrawn from a race, the odds for all bets placed on remaining horses are adjusted to account for the non-runner(s). This is because less horses in a race increases the probability of each remaining horse winning.
Rule 4 or Rule 4(c) of the Tattersalls Rule of Racing, as it's officially known, is observed by the betting industry to protect bookmakers in the event of a non-runner or non-runners after the final declarations for a race are made.
Trifecta Box Betting
For example, a $2 three-horse trifecta box costs $12. Adding a fourth horse bumps up the price to $48. These are not cheap bets, but they are effective and can potentially yield a large payout for winners.
That's where you pick three horses and bet every possible combination of first, second, and third. It will cost you more because that's technically six bets. So, a $2 bet becomes $12. You can also add more horses for more money.
While straight trifecta bets involve picking exactly three horses to finish a race in first, second, and third place in that precise order, trifecta box bets can include three or more horses and cover all possible winning combinations.
But to box the minimal number in a first 4 you will pay four times as much. Interestingly, if you box four horses in a trifecta, it will cost you exactly the same as boxing four in a first 4, but any increase in the number of horses will do amazing things and create huge differences.
A First Four is an exotic bet type that requires the punter to select the horses that finish 1st, 2nd 3rd and 4th. This bet type is very similar to a Trifecta, which requires the punter to select the horses that finish 1st, 2nd .
