Hi all,

I just want to use this thread to test out something. I've now got access to sectional times in a reportable and query ready format. This allows me to test some of my theories about race pace in a more systematic approach.

This thread is looking at the systems, every week I will try and post some rationale behind a system and also the day to day bets that it throws up

The goal of this thread is to return a profit of 500pts. The bank for the thread is 1000pts and each bet will be likely be 2pts win at Betfair SP.

So lets see how we get on.

System 1 - Turf Sectional Upgrade

13:20 Nottingham Legacy Power Turf - Sectionals - Upgrade LTO
15:20 Haydock American Bay Turf - Sectionals - Upgrade LTO
19:00 Leicester Delicacy Turf - Sectionals - Upgrade LTO
20:30 Leicester The Ormer Gatherer Turf - Sectionals - Upgrade LTO


This system has had a small 8% strike rate over the test period, but has a healthy P/L at Betfair SP, Early Price and Breakfast Price.

The key to this system is that it has had an average odds of 42.73 BSP, and an average winning odds of 17.68.

The system looks at horses whose last run had a sectional upgrade of more than 2 lengths, meaning that if they had run the optimum line, or the optimum race conditions had been run, they would have finished two lengths closer to the leader.

The premise of this system is to find horses that were beaten last time out, but hadn't had the race run to suit them. The hope being they are not well found in the market.

I have this down as a risky system, but the potential for big positive results are shown in the test data.
 
Sectionals - Lead and easy Lead?

13:55 Nottingham One For Harvey Sectionals - Will they lead and get easy lead?
16:45 Lingfield Twilight Madness Sectionals - Will they lead and get easy lead?

I will write that system up tomorrow or later next week.

Very interesting. Can you apply the same theory to the other runners in the race in which the horse got the sectional upgrade (eg to check that it would have been 2l closer if the same argument applied to the winner; and to see where the other runners would have finished with the same argument applied to them). That would be fascinating as you could effectively run the entire race again

It might also be useful for finding over priced favourites/near favourites (ie a winner last time out but has a sectional upgrade that would have made it an easier winner than it looked)

Will you be applying this "blind" or will you also take account of other things such as jockey change, change of ground conditions which may be more or less suitable, whether the horse is progressive or fully exposed, different distance *etc etc? Combining the sectional upgrades with upgrades/downgrades for other factors such as those mentioned could maybe throw up a few worth an extra stake

Looking forward to the theory of the other system

EDIT. * PS horse ran green, looked as if in need of race

On the first one, yes, it shows the finishing positions after upgrades too, so you can see horses who were potentially unlucky, or got the run of the race.

I tend to follow them blind, but I've also got others that indicate something to look at, so it depends on what the situation is. The change of ground for instance is something I have spent a lot of time looking at for indicators for which trainers do best when the ground changes. It will be interesting to see that with the sectionals added.

Yeah, was a very nice ride by the lad. Betfair SP of 8.2 makes it profit for the day. Two to run this evening, hopefully one of them can trouble the judge. Probably not the 50/1 shot!

Results

Day 1 -

12 pt staked

2 winners - One For Harvey @ 8.2 returning 15.92
Delicacy @ 5.66 returning 11.13

Bank +15.05



Day 2 Selections

14:50 Newcastle Not Me All Weather - Sectional Upgrade - NOHG
16:35 Newcastle Sam Hawkens Sectional - Longest Stride last furlong but didn't win
16:35 Newcastle Arrange All Weather - Sectional Upgrade - NOHG
17:45 Newcastle Atlantic Gamble All Weather - Sectional Upgrade - NOHG
18:15 Newcastle Party Bear All Weather - Sectional Upgrade - NOHG


The sectional upgrade is the same as with turf runners, so no need to go into that.

Longest Stride last furlong but didn't win, is what it says on the tin. The idea here is that horses who finish with the longest stride in the final furlong are showing that they aren't tiring as much as others in the race and are maintaining their effort.
 
So 10pt staked for the day. You'd be looking at Sam Hawkens and Party Bear as the likeliest two, but lets see!

Best of luck Nass.

This data you have access to - I assume it is behind a firewall?

Yeah, it is all password and site protected. Interestingly the source data is TPD, which feeds the very good sectional section of At The Races website.

Another winner today, with Sam Hawkens winning for the stride system at 7.5 Betfair SP.

Without getting too fanciful, surely it must be possible to programme AI to sift through the data, pick out the horses to bet on (based on a staking plan that the AI can learn) and place the bets? Could be something of enormous value.
 
So Day 2 had one winner at 7.5 Betfair SP,

This returned a profit of 4.99 points for the day.

2025-05-10 15.05
