Create your own speed ratings

Over the last few years I have created a number of different ratings for our own use and clients but these have all be form related.

So I guess it was only a matter of time before the question of speed ratings came up.

Some people argue that speed is the only real way to judge a horses chance of winning a race…

But as with all things racing, it is never quite that simple.

Speed of course is related to distance.

It is the time it took the horse to run the race divided by the distance that gives us the speed at which the horse travelled.

Place Ratings

Today we have our regular Wednesday column from Malcolm Pett of http://greyhorsebot.com

Using ratings to find selections to place

I was never really interested in the place market on Betfair until recently.
But while working on a new ratings system I noticed a trend that got my attention.

Lately I have got very interested in high strike rate systems that normally select runners that are ranked 1st to 3rd in the betting.

Admittedly these are not the easiest systems to make money with but they can be a little more interesting to follow than your average “One a day” wait for a winner type system.

I am not knocking this type of system as I run many of them myself. I am just saying that sometimes it’s nice to have a few more selections that seem to win very often.

Over the last year or so I have been creating quite a few rating figures based on different ideas and I have shared some of these with Grey Horse Bot users.

The idea of creating any ratings is to help you identify potential winners but I think “help” is the key word…

…They can be useful in helping you to narrow down the field and letting you concentrate on just a few selections in each race.

In my last couple of articles I have mentioned that I was concentrating on the top 3 in the betting as ranked by the BSP prices early in the morning and I wanted to carry on with that idea.

I tend to try and make it a little easier on myself like sticking to “Handicap” races only as I have in this case.

As a programmer with quite a large database of results and information to use I am lucky in the sense that I can come up with ideas and then test them quite quickly.

But you should never forget the fact that humans are very good at noticing patterns.

I make sure I spend a great deal of time just looking at my ratings within the context of a lot of other racing information, just to see if I notice something that I may not have seen just by looking at individual numbers.

And this is what I was doing while looking at my latest ratings.

It appeared that the selections that I had been highlighting (I use yellow normally) to show me strong selections (although were not winning all the time) did appear to place.

Of course nothing is ever that simple and the next thing was to discover if I could come up with a way of identifying enough winning selections to make money.
And that’s where I am at the moment.

I have a list of daily selections and I have to decide which ones I am going to place.

With a couple of rules I am able to either discount the race entirely or select just one runner to follow.

If you would like to see the daily selections and the ideas I have come up with then pop over here for a look. Click Here

You can look back to the beginning of this month at the moment to see if you can find anything yourself.

Thank you as always for reading I really do appreciate it.

National Hunt Trainer Facts

This morning I'm trying to get a handle on where I want to go with a new National Hunt system, so I'm looking at some facts and figures in the hope that an idea of angle jumps out at me.

So I've logged into Horse Race Base and loaded up all Hurdle runs in 2013 and so far in 2014 and I'm looking at the trainers to see where the best returns are.

If I look at trainers that have had more than 75 runs since January 1st 2013 and sort them by strike rate, then the trainer with the highest strike rate is Willie Mullins…

Runs = 641

Wins = 186

Strike Rate = 29%

Loss at industry SP = -124.03

ROI = – 19.35 %

I'd say a strike rate of 29% from all hurdlers sent out is huge. A loss of 19.35% on turnover is a lot, and although I'm sure that can be improved by betting at Betfair SP I would imagine a lot of these were favourites and that the Betfair SP returns wouldn't be a great deal better.

Interestingly, just down the list a bit is Nicky Henderson with a 24% strike rate but only a 7% loss on turnover…

Runs = 525

Wins = 125

Strike Rate = 24%

Loss at industry SP = -36.75

ROI = – 7 %

So my next task is going to be to have a closer look at the hurdlers of these two trainers.

First off, I'm interested in how many runners Willie Mullins actually sends over to the UK and whether they perform better or worse than his Irish runners.

The answer is that only 61 came to the UK in the period and the strike rate with these 61 was 21% and the loss of turnover was 29%.

So the profit and runners will be in Ireland.

The table below shows the breakdown of the Irish runners by track, you will see there are some huge strike rates at some of the courses…

Willie Mullins Irish Course Run 2013 - 14 table

Next I looked at position in the odds market and this is interesting out of the 580 runs that Willie had in Ireland since January 1st 2013 a whopping 469 were ranked in the first four in the betting market.

How many that were not in the first four in the betting do you think went on to win?

Well according to Horse Race Base the answer is none!

In fact if we only bet Willie Mullins hurdlers that run in Ireland and are in the first three in the betting then we have a system that just edges into profit at Industry SP.

If we only look at those ridden by Paul Townend or Ruby Walsh, who take most of the rides then we have the following figures since January 1st 2013…

Runs = 331

Wins = 139

Strike Rate = 41.99 %

Profit at industry SP = 22

ROI = 6.65%

That's a great strike rate and if you can't stomach losing runs then these rules will find you bets that see you collecting regularly, but these horses are over bet, especially when Ruby is on board, so the profit isn't huge.

Horse Racing Ratings

Grey Horse BotToday we have our third guest column from Malcolm Pett of Greyhorse Bot fame.

—–

It’s strange how you see yourself…

I have always thought of myself as out going sort of person who likes a challenge and is not afraid to try something new.

Although I haven’t done as much as some people, I have had my fair share of adventures including, windsurfing, flying lessons, Scuba diving and sailing. Those are among some of the things I have tried and learned.

But while talking with some friends who I have only known over the last few years they said I was more of a “nerdy” type of guy.

When I quizzed them about why that was their impression of me?

Their answer was simply I am always talking about computers, programming, databases, 3d printers and lately quadcopters….. Nerdy!

Although I thought about defending my own impression of myself I have to admit…

…As the one that my friends tend to ask about anything technical it was going to be a hard battle to win.

So “Nerdy” I am…

To be honest I actually don’t mind the term although I am probably not exactly as some on-line dictionaries explain it…

“A person who is single-minded or accomplished in scientific or technical pursuits but is felt to be socially inept”

Any one that knows me will certainly not call me “socially inept”.

“One obsessed with something specified: a computer nerd.”

Which is probably what my friends were thinking when they used the term.

So when I start talking about System development or statistical modelling then you will probably think the same.

One of the things I love doing as a “computer nerd” is analysing our in house database to find horse racing systems.

Horse Racing Ratings

Lately I have been spending a great deal of time on developing ratings.

This is where you actually assign a number to each runner in a race and then rank them by that number or simply use the rating you have assigned them.

The official rating (OR) which you find on race cards is an example of this…

The fascination is in the way you create the ratings.

A trick you may want to use is to combine a number of ratings from different sources to create what some people refer to as “Power Ratings”.

So you could use the OR, RPR from the racing post and another rating like Sporting Life’s 5 star rating.

Add them altogether and you have ratings from 3 different sources which may point to another winner rather than the favourite.

I would suggest sticking to handicaps when you begin purely because all runners tend to be rated unlike say “maidens”.

I have tried this myself in the past and it can work quite well but the downside is the work involved getting all the information together daily.

I much prefer automation, and because of that I like to build my ratings based on statistical information.

Like…

How often a horse that came 1st place last time out…Wins.

Or

How often a 3 year old Horse wins a handicap.

You can see an example of how you could do it here.

See the ratings

I am a great believer in ratings (not just because I am a nerd) because I feel they give you a consistent way of selecting runners which tends to also give you a consistent strike rate.

The trick is to find the ones that offer value.

Thank you as always for reading I really appreciate it.
