In the final instalment in this series, today I will discuss betting with ratings. As a long-term professional punter this is obviously a subject I feel well qualified to talk about.



There are many ways to implement ratings and the approach you take really depends on the individual. If the rated markets are framed to a percentage of less than 100 (say 95%) it means is that if you were actually able to secure the rated price on each runner to collect $100 then you would be spending $95 and showing a profit of $5. If you secured overlays the profit margin will be even greater.



Of course it is most unlikely that you will experience a 95% market, even if you shopped particularly well securing the best prices offered amongst bookmakers, Betfair and best tote. In saying that, markets of less than 100% can occur very occasionally and when it does you are in a win/win situation for no matter what the result of the race is, you will make a profit.



In a normal 100%+ market you need to formulate a plan as to how you intend to invest into each race and that plan will differ from race to race. Lets say in a particular event with nine runners the assessed chance of each horse (in a market framed to 95%) was as follows.



Assessed 95% Bet reqd to collect $100 Actual Market
1. $2.50 $40 $2.30
2. $4.00 $25 $4.50
3. $10.00 $10 $7.50
4. $12.00 $8.50 $16
4. $20.00 $5 $12
5. $25.00 $4 $16
6. $40.00 $2.50 $25
$95.00



In the above race the two horses that are over the odds are #2 and #4. One strategy would be to back them both to win a percentage of your starting bank, which for the sake of this exercise is $100. The bets would be $25 and $8.50 win on #2 and #4 respectively.



If #2 wins the collect will be $112.50 and if #4 wins $136.00. The area that many punters have difficulty understanding is that in a situation like the one above you should not be backing the top-rated horse. While it is assessed as having the best chance of winning the race, it is not a value bet at the available odds.



Rated at $2.50 its chance of winning is 40%, so over 100 races it is expected to salute 40 times. Taking unders at $2.30 will return only $92 per win x 100 races = $3680.
The outlay of $40 x 100 races is $4000 so over a period of 100 races you can expect to lose $320.



Alternatively the chance of # 2 winning is 25% (calculated by dividing its rated price into 100). So over 100 races the outlay would be $25 x 100 = $2500. The return would be $112.50 x 25 which is $2812.50. This leaves a profit of $312.50 less the amount invested on # 4.



This is the principle behind obtaining value and it is no different to the example used of trying to get odds of more than $2 about a coin toss. Securing overs does not mean the horse will win, nor does it mean the horse has a better chance of winning. More importantly though, it means that in the long run you will win.



In the short-term you will experience losing bets and losing runs, but by combining a consistent staking plan with a disciplined approach you will end up with a positive result.
