# Misleading Stats (Part 2)

Win strike rate is simply calculated by taking the number of races a horse has won in its career and dividing it by the number of starts it has had. For example, a horse with two wins from ten starts has a winning strike rate of 2 / 10 = 20%

The late Don Scott was a big believer in the proven winning ability of a horse being a key factor to consider from a betting perspective. He wrote in his popular book Winning More, “the best horses to back are horses whose wins are frequent and predictable. The worst horses to back are horses whose wins are infrequent and unpredictable.”

His theory seemed entirely logical and to this day punters still largely consider a high win strike rate a positive for betting and low win strike rate a risk.

However, research of the facts around horses win strike rates paints a different picture. It shows that a bias towards high win strike rates compared to lower win strike rates is unlikely to be adding any value at all to your betting profits and is more likely to be limiting your ability to find good value bets.

The table below shows horses up to \$10 SP in non-maiden metropolitan races with at least 10+ starts in their career.

We exclude maiden races as by nature every horse in them has a 0% win strike rate.

We isolate those with 10+ starts so that we can draw conclusions on an exposed group of horses without the statistics being incorrectly influenced either positively or negatively by lightly raced horses.

For example, a horse with 12 starts and a 50% win strike rate (6 wins) is entirely different to a horse with a 50% win strike rate from 2 starts (1 win.)

Equally, a horse with zero wins from 3 starts shouldn’t be viewed as statistically equal to a horse that has zero wins from 15 starts.

Win SR% Runs Wins SR% POT%
0% – no wins 150 26 17.3% +48.8%
1% to 10% 5363 818 15.3% -2.5%
10.1% to 15% 8089 1213 15.0% -3.1%
15.1% to 20% 12658 1953 15.4% -7.%
20.1% to 30% 13955 2290 16.4% -7.6%
> 30% 7907 1523 19.3% -7.5%

There are very few horses with a 0% strike rate because the vast majority of horses racing in a non-maiden metropolitan race have already won at least one race. That extreme positive result with a sample of just 150 runners is relatively meaningless.

What is very meaningful though is the record of low strike rate horses in the 1% to 15% range when you consider it is metropolitan racing and the horses have all had at least 10 starts.

Their strike rate is only marginally less than horses that win more often, but their betting returns are 2-3 times better.

The table clearly shows that the best betting returns actually come from horses with a lower strike rate. The betting market perceives a low win strike rate on well exposed horses as a distinct negative and offers a slightly better price about them. The truth is that it’s barely a negative at all as far as win strike rate goes and the net effect is a much better return to punters.

There’s no doubt that consistency in a horse is an asset, but the key message here is don’t use simple win% or even place % statistics to judge that. Look at the quality of a horses past runs and competitiveness, especially in races of similar grade to the upcoming one and judge for yourself how consistent they’ve been.

If a horse has the right form and other credentials for a race, then a high win strike rate does not make it more appealing as a betting prospect.

Even more importantly, don’t be biased against a horse that otherwise looks a good bet because of a low win strike rate. Embrace those betting opportunities, because history very clearly shows that you are likely to be getting an extra few percentage points of value in your favour.

### Previous First Up Record

First up horses always present some uncertainty and the first point of reference for a punter is to check the horse’s previous first up record.

This is however one of the more misleading statistics in the form guide. Let’s break down the stats for first up horses up to \$10 SP in metropolitan races.

First Up Form Runs Wins SR% POT%
Never won first up before
1 prior run – 0 wins 2349 428 18.2% -7.7%
2 prior runs – 0 wins 1439 248 17.2% -1.3%
3+ starts – 0 wins 1215 206 17.0% +13.8%
Has won first up before
1 prior run – 1 win 1242 287 23.1% -1.6%
2 starts – 1 or 2 wins 1721 312 18.1% -10.3%
3+ starts 1 or 2 wins 3174 467 14.7% -12.6%
3+ starts – 3+ wins75 417 75 18.0% -13.5%

There is a general pattern here that the more impressive a horse’s first up record gets, the worse the betting returns are for all of those horses as a group. On the flip side, the best returns come from horses with 2+ first up runs in the past for zero wins.

Let’s summarise that table to make the patter clearer and also look at a horse’s previous place record when first up:

First Up Form Runs Wins SR% POT%
Never won first up 5003 882 17.6% -1.5%
Never won or placed first up 1825 314 17.2% +0.2%
Has won first up 6554 1141 17.4% -9.5%

First up horses that have never won or placed before have an identical strike rate to horses with a previous first up win, but the betting returns are significantly better.

Remember that we are looking at first up horses that are considered a genuine chance (up to \$10) in the betting market. They are all likely well enough credentialed in terms of class, distance of the race and other factors… but there is a clear and incorrect bias by the market that overvalues the important of previous first up wins.

The problem with using first up statistics is that they ignore the class of race that record was earned it and that’s especially relevant when analysing metropolitan racing.

A horse could have a first up record of 2 from 2, but if they were earned in a Country maiden race and then Provincial restricted race, how relevant is that to a first up city class race?

The message is clear. Don’t get carried away with first up statistics. Look beyond them to the class and quality of a horse’s previous runs when first up. Review trials and other information (e.g. jockey booking, support in early markets) to make your judgements about how ready a horse might be to run well.

If you like a horse that is first up, then the last thing you should do is let its lack of previous first up wins or placings put you off. If anything, you should bet with some confidence knowing that the market will be incorrectly biased against that and likely giving you better value.

### Barriers

The universal theory that an inside draw is an advantage in racing and an outside draw is a disadvantage is incredibly limiting when it comes to punting.

The influence of barriers are very much a track / distance specific thing, but a general analysis of inside versus outside barriers at Metropolitan tracks helps to demonstrate the point.

Races up to 1200m

Barrier Runs Wins SR% POT%
1 to 3 10587 1993 18.8% -6.2%
10 or wider 3846 616 16.0% -2.9%

While the strike rate of wider drawn horses is marginally lower, the betting return is more than 2 x better. This shows that the market is biased against wide barriers, but it overcompensates too much in its pricing and provides a much better than average return.

The picture is even more significant is races from 1400m to 1600m.

Races from 1400m to 1600m

Barrier Runs Wins SR% POT%
1 to 3 8045 1454 18.1% -4.6%
10 or wider 3699 598 16.2% -0.4%

The return from horses drawn wide up to \$10 in the market is significantly better than those drawn inside.

Races 2000m and beyond

Quite interestingly, we often hear that barriers in staying races matter far less than Sprint races, but the data would seem to pain a different picture:

Barrier Runs Wins SR% POT%
1 to 3 3405 640 18.8% -6.3%
10 or wider 1363 199 14.6% -12.8%

The samples here are small, but a check back to 2008 (the last 10 years) show the results are consistent. Neither inside or outside draws provide better than average returns, but it’s clear that wide draws do return much worse than the average.

These are broad generalisations across all metropolitan tracks and it’s important to recognise that the most insightful view on the influence of barriers will come from understanding the specific track / distance and more importantly the racing style of a particular horse and structure of the speed map. A wide drawn horse that is the only horse with decent early speed in the race should be viewed entirely differently to a horse with moderate early speed that has a number of faster horses drawn inside it.

An inside drawn horse that lacks early speed and could end up buried on the fence in a large field is entirely different to a horse that has the speed to box seat in a moderately run race.

The key message is that you should let go of any universal beliefs you hold about the importance of inside versus outside barriers.

You should especially avoid being biased against a horse simply because it has a wider barrier. Historically they provide much better than average returns (except in staying races) and in the right circumstances can help create terrific betting value about a horse you like.
