What Is A Horse Racing Rating?

Ratings are a very mis-understood medium in betting. They are however exceptionally powerful if used correctly. Today I want to make sure that you don’t fall into the biggest trap that most punters do when using ratings.

You cannot get away from ratings in horse racing. They are part and parcel of what horse racing is. If you look at the Racing Post there is the Official Rating, RPR, Top Speed amongst others. This means that if we want to progress our betting we need to understand what these ratings mean. And by understand I don’t mean have an idea what it is measuring, but really understand how ratings work.

I am going to kill the biggest myth right now…

• The top rated horse is NOT necessarily the best horse in the race

At first glance this sounds like an illogical statement. After all, if it’s top rated then surely it is the best horse in the race?

No, this means it is top rated for one rating which tells us that this horse is the best horse in this race for whatever it is that this rating is measuring. However it may be joint best. Ratings are estimates of either an aspect of a horses performance in a race or a prediction of an aspect of a horses performance in a race. Either way the key word to note is that they are estimates. This means that there is going to be a margin of error in them. The error can either work in our favour or against. By this I mean the horse could be slightly under-rated or over-rated.

If we take into account that there is a margin of error around a horses ratings then we can immediately see why a horse may not be top rated.

In the screenshot above you can see a random race I took from the Racing Post. Notice that Desert Sunrise and Forceful Flame are top-rated for RPR. Then we have three runners in Seven Of Clubs, Sakhee’s Rose and Kodatish that are joint second-rated. If we were following the thinking of most punters then we would assume that these runners are not as good as the first two.

However we aren’t normal punters. We’re better than them and we know that these ratings are estimates. If we allow just a 5% margin of error, which is probably too little, then the horses rated 84 could have a real rating as low as 80 and as high as 88. The horses rated 83 could have a rating as low as 79 and as high as 87.

So the top two horses are likely to have a real rating between…

80 – 88

The second top three horses are likely to have a real rating between…

79 – 87

Looking at those new ratings would you be so confident that the top two rated are the best horses in the race?

Based on this new information we can see that in fact the top 5 runners are very closely rated in this particular factor. In fact the other runners in the race are not that far below either when we apply the margin of error. Suddenly this race becomes very competitive if we are only looking at the RPR for information. This is backed up by the fact that a horse rated 82 won the race.

This is the reason that we cannot rely on a single rating to make our selections. We need to look at a range of ratings that measure different aspects of a horses performance and allow for a margin of error in the ratings creation. When using ratings we ask ourselves…

• Which horses are best suited to all the conditions?
• Which horses are best suited to the most important conditions?
• Which horses have the best overall figures?

Start using this in your betting and you will start to see that races are more competitive than they first looked. However this works both ways. You will also begin to see races where the competition is a lot lower than it initially looks and you can target these races for your betting!
