View Full Version : Betting AFTER the win.

No, don't get your hopes up I haven't found a way to che&t the bookies. If you get through this though there may be something worthy of your interest. I've capitalised the juicy bits for those with a short attention span.:)

I've noticed as part of some systems on here that people recommend things like "Bet on the favorite but only after a favorite has won at that meeting". Other's have said "Bet in such a fasion but stop after the first win". These two almost opposite approaches, both possibly valid in their own context, interested me but weren't of any immediate use so I stored them away at the back of the mind until later.

Anyway, I've been betting quinellas lately and noticed that wins seemed to be clustering within meetings. If you had five wins across 7 meetings they wouldn't be evenly spread there would often be a couple of meetings with 2 wins or maybe one meeting with three. So I decided to investigate. I ran my system as it would have worked over races since 1996 to find the returns I would have got and then ran it again only betting when a quinella had turned up at the meeting.
NSW Races showed an increase in ROI from 117% to 123% (100% means getting your money back, 200% means doubling your money).
WA Races went from 119% to 121%, QLD from 116% to 126% and Vic races from 114 to 119%.
So, a definite improvement on four independant sets of results. Interestingly the strike rate in three of the four actually went down a little so the dividends were improving at the expense of strike rate. Also the returns on races since January 2006 were much better in 3 of the four sets of figures which is probably why I noticed the clustering.

Encouraged by these results I decided to see if it worked on win bets too. These figures by the way are based on my ratings, I'll get to some figures on favorites later.
On win bets across the four states I didn't seem to improve much. WA went up a couple of percent, NSW 1% and Victoria down 2%. Again though with all results the strike rate went down. 1% less winners in all states except WA where it was about 0.1%. Divies were compensatingly higher after the first winner so I was making about the same ROI but just betting less.

I was intrigued by this point as to why the results were as they were. Why did the strike rate always seem to go down and why weren't my winners improving if the quinellas did. So I decided to analyse the same thing betting on favorites.
The program I have which analyses bets on favorites isn't as versatile as my other program so these results are only done on NSW races but there are over 70,000 of them so it's still a pretty valid sample.
If you were to bet on the SP favorite at all NSW races you would score 34.35% winners, 33.32% if you only bet on races where the NSW tab recognises the meeting. If you wait until the first favorite has won at the meeting you would only score 33.14% and 32.03% winners respectively. Again the strike rate goes down by 1%. The ROI from these bets drops from 89.47 to 88.58 for all races and 89.84 down to 89.55 for Tab Races. So, YOU DON'T IMPROVE YOUR RETURN ON FAVORITES BY WAITING FOR THE FIRST FAVORITE TO WIN.

Next I tried the other end of the scale. What happens if you bet on the longest priced (SP) horse on all races and after the longest price horse has won.
Well, at all meetings your Return from backing the longy is about 36% of your cash and at Tab meetings about 44% of your cash. If you wait until the longshot has won a race and then bet those that run after it rises to 43% and 56% respectively. Even more significantly the strike rate IMPROVES after the first longshot has won, the only time that happens in all my sets of figures. The number of bets is drastically reduced, it's a long wait for the longest priced horse to win at a meeting before you make a bet but: IF YOU'RE BETTING LONGSHOTS YOU HAVE A BETTER CHANCE OF WINNING AFTER A LONGSHOT HAS ALREADY WON AT A MEETING.

Finally, I'm a programmer and I know we put bugs in programs just so we can make money from doing software support so I ran another test to see if the program seemed to be working. Besides I was still intrigued about the strike rates falling consistently after a winner.
I did the test (on NSW races) using the earliest and latest horse in alphabetical order as a sort of random horse thingy. On both start of the alphabet horses and end of the alphabet horses the strike rate dropped from about 12 to about 11.5 percent winners if you waited until one of their fellows had won a race before having a bet. The ROI didn't really change much (up a little on one, down a little on the other).
So what did I learn from this? I suddenly thought that the strike rate must be dropping because there are more horses in races later in the program although the ROI on a random horse stays about the same.

OK, Draw what conclusions you like from these results (if any). I found them interesting and I've concluded that:
1. Favorites win at the same rate independant of whether a favorite has already won at a meeting.
2. If a longshot has got up there is now a better chance of a longshot getting up from now on.

How do I explain the quinella improvement but little win tote improvement which started this whole train of thought? Well if lesser fancied horses are winning in clusters that is more likely to affect exotics where you are relying on the performance of multiple shorter priced horses (i.e. there is more potential for a longshot to find its way into the first two or three).

I'm going to try to attach a results sheet of the full results but don't know how I'll go. Nope, it's 40K so it's too big - I'll email it if anyone wants it.

A couple of queries regarding that longshot part. What was your definition of a longshot? What sort of price? And would you have any way of finding out what part the state of track played in that? Perhaps longshots won more frequently on wet tracks?

That's a LOOOONG story Sportz.
I hope you win millions of dollars.
Just remember ,I like you a lot and if you do win millions, I only need about 100 grand.
Thanks Sportz..GOOD LUCK!

OMG!
Kenny Victor you the one.

Kenny I good friend of Sportz.
Maybe 10 grand?
I will say a nice prayer for you and your family.

Yeah Mo. Believe me, if I'd written that LOOOONG story, I think I would have remembered it. :)

Hi Sportz,

The longest of the longshots - The horse with the highest SP. Could be track related I suppose. Don't know whether you would get a meaningful answer because the sample size is getting down with backing THE longshot after THE longshot has already won. It doesn't happen that often (1544 times in the last 10 years NSW races).

Well, I think the rank outsider of the field has probably just won the first at Taree. Is that what you're referring to? So in the case of your study, you would back the rank outsider at Taree from race 2 onwards?

Hi KV!
I have done the same study, some time ago, on horses paying between $10 and $40.
I had the same outcome but far more pronounced. It's a definite goer, must have to do with the track on the day or how the races were run.
From memory there were a couple of meetings last week? maybe Morphettville and at least an other one where two or more longsots won.
Going over $40 or maybe $50 is a bit more risky, they just do not win often enough. As to wet tracks? I think favs win far more often on wet than on any other track. Haven't done the numbers but I am almost certain.
Cheers.

Sportz

Yes, that's right. Favs do actually win at a higher % on wet tracks, BUT I suspect there is also perhaps a higher instance of big outsiders winning. Not sure though.

Sportz,
No mate, still wouldn't back it just coz it's the longest. I reckon only 43% of your money comes back betting on the longest priced horse usually but it improves to 56% now that one has already won. If, as Marcus suggests, the same thing holds true of long prices generally (as opposed to the LONGEST) maybe just the longer priced horses in general might be a good bet now.

Marcus,
Interesting stuff. I just tried the extreme end of the scale which didn't actually show any way to make a profit, maybe there is more future in just "longish" priced horses.

Moeee,
Thanks for the offer of the 10 grand but I just did it for the love of the sport and to try and enrich the life of my fellow man. My family appreciated your prayers, little Jacob with the mangled legs has suddenly started walking again so I think they worked.

See Pakenham yesterday, 3 in row over $20.
I might just spend some time on this!!!

Wasn't thinking of backing them. I was simply asking if that was the circumstances that you measured in your test.

A thousand pardons Sportz I read your post too quickly and misunderstood the gist of your question. Yes, that's exactly what I would do in the context of the test.

As regards track differences - I've run the figures on NSW races using the SP to find the favorite or longest priced horse and the returns based on the NSW TAB payout.

Longest priced horses return.

about 56% of your cash with a strike rate of 2.33% on heavy tracks.
about 53% of your cash with a strike rate of 1.51% on slow tracks.
about 41% of your cash with a strike rate of 1.08% on dead tracks.

about 42% of your cash with a strike rate of 1.13% on good tracks.


Favorites return.

88.02% of your cash with a strike rate of 31.18% on heavy tracks

89.77% of your cash with a strike rate of 31.89% on slow tracks

89.37% of your cash with a strike rate of 32.76% on dead tracks

90.23% of your cash with a strike rate of 33.83% on good tracks

Not a great difference with favorites but the longshots seem to do better on worse tracks.

Hi KV!
Flemingtom today!
Two over tens, and kabooom, a $68 longshot. That will do me.
Although, why Roman Arch was at those odds beats me? I had it as a third selection, but that's beside the point!!!

Good on ya Marcus. I mean to test this multiple longshot thing when I get time. Can't say I agreed on Roman Arch, I had him gasping for breath 6 and a half lengths behind the winner so I certainly wouldn't have picked him on ratings alone. But still, I didn't lose any quinellas at Flemington because I never got a first one to come up - didn't even come close, which might explain my failure on RA.

Hi KV!
Know what you mean! I will do it myself soon, lucky I only bet on a limited number of meetings, I don't think it would work, betting on every meeting, every race. Not having done the research I just don't know.
As to Roman Arch, we all have a different approach to rating.
Sometimes I am right, other times you are.
Wish we all would be right a bit more often though??
Cheers
