Because today is a public holiday in WA I decided to do a bit of research on the Tabform ratings which are also the Unitab ratings. Are they in fact AAP ratings?
The results of the last 5 months for this system are 99 selections - 14 winners - avge divy $13 - LS profit 81 units.
The best winner was Roman Arch in Melb in the spring - $23.
You would need a big heart to follow a system with such a low strike rate but it achieved a good result if you had done so.
Will it continue to succeed? Probably not, but I've backed Sportsman ($17 winner)and Wishart ($14)from a handful of bets in the last couple of weeks so I'll continue on until the profits run out or ...... .
The rules -
Metro Sat only excluding Adelaide and Perth.
Consider any 100 pointer left after scratchings.
Back it if you can obtain $8.50 or more.
Ignore races where 3 100 pointers are >= $8.5.
I know that Sportz and others have looked at 100 pointers so if any of you have some extra rules which would improve the bottom line feel free to jump in.

Any idea how that system would have gone at country and provincial meetings? Desert Clearance a 100 rater just got up at Sale paying $8.60 here in Qld!!!

Anyway, I love the Unitab ratings and I've got one for you to look at:

1. At least 8 starters after scratchings.
2. Horse must be the only 100 rater left after scratchings.
3. Must be first up from a spell.
4. Must have won at this distance (c or d).

In the last 3 months, that simple system made around 85% profit and it also picked Sportsman.

Your system looks pretty good as it is, but if you want to improve things, I suggest you could look at winners at this distance (c or d) or last start beaten favourites.

Sportz
I knew that you'd have some good ideas to contribute. The distance winner seems like a good angle to look at. I'd like to get the hit rate up to 20% if possible even if it sacrificed some of the profit. I'll look into it when I continue my research.
I must confess that until this morning when I was doing the research I didn't know that unitab had ratings on C or P meetings. We get them for Sat meetings only in the TAB form guide. Something you wrote elsewhere made me think that they were perhaps the same as the unitab ratings and a spot check seems to confirm that.
Do you have the breakdown of win% etc for the first up system? It looks like a good one and shows your genius for finding 7 day a week systems. I have the utmost admiration for someone who can do this.

Around 30%.

I'm sorry, I haven't actually updated my figures, but up until last week, they were like this: 16 wins from 52 bets and a profit of 86%

I personally use a pre-post price range of $3.00-$21.00 and using that, the figures are like this: 14 wins from 46 bets and a profit of 101%

Hope that helps.

[ This Message was edited by: sportznut on 2004-03-01 16:02 ]

Okay, not quite so good in the past week or two. Here are the updated figures:
Selections 59
Wins 18, Win return $102.30, Win profit 73%
Places 34, Place return $66.00, Place profit 12%

With $3-$21 pre-post price rule:
Selections 52
Wins 15, Win return $96.40, Win profit 85%
Places 31, Place return $63.90, Place profit 23%

As for your idea, I think it's an excellent one. As I was going through a few results yesterday, I noticed many good priced winners from the 100 raters on all days of the week. I'm going to have to look into that. :smile:

[ This Message was edited by: sportznut on 2004-03-02 09:43 ]

Sportz,
Just curious do you check the selections 1st up strike rate or just bet them if the above rules apply.

Cheers

Good point. No, these results are without checking for first-up strike rates. I'll have to look into that too. :smile:

Sorry, not at the moment. However, I am working on these 100 raters systems at the moment and by the time I'm finished, I'll have some figures for you. :smile:

Sportz....in the above results what was the test period of those selections
how many selection a day would you say

Shaun,
It's actually 100 days since the start of the test period, so about 4 bets a week.

Kenchar,
I've done a check and some of the winners hadn't even been placed first-up before. Having said that, horses with a good first-up strike rate were a bit more consistent, so I've used a rule that I often use for first-uppers to try to sort out the best bets:

At least 3 first-up starts, and at least 50% wins or 75% placings from those starts.
Nov20 CHbr 7-3 Papal Prince UNP
Nov29 Adel 4-5 She's My Baby WON 3.00/1.60
Dec13 Adel 8-4 Crest Of Gold WON 2.50/1.40
Jan23 Melb 4-5 Yell UNP
Jan25 MGam 2-2 Andalan WON 2.00/1.10
Jan27 Bena 8-1 Majestic Flush UNP
Jan28 Sydn 5-3 Beryl WON 5.50/1.90
Feb3 Melb 3-2 Penny Opera WON 3.70/1.40
Feb7 Melb 5-1 Lonhro WON 1.70/1.20
Feb11 Sydn 7-6 Derby Parade WON 7.50/2.30
Feb14 Sydn 6-1 Private Steer WON 3.10/1.50
Feb14 Sydn 7-3 Sportsman WON 17.40/3.70
Feb15 Colac 8-4 Ski Rebel PLA 1.50

Looks good!!! :smile:

hi sportz, the unitab ratings are a good guide as u say and here is one that i have found seems to produce a place strike rate of over 50 % and ave divi around $2.50.
it also gets some good price winners but dont have stats on winners.
look at 3rd and 4th raters take the longest price of the two on unitab just prior to jump time providing it is$5.00+for the win.
if there are 2 on the same rating that counts as one.
i use it only on saturday but it may well work on other days as well.

Sounds a bit like Kenchar's place strategy. Might be worth a look.

I checked another month on the original system which produced two winners and a LS profit of 11 units.
That's 92 units profit over 6 months.
I'll continue on until I've done 12 months.
Both winners, Sportz, had won at the distance.
Please note that I've made a minor amendment to the original post eliminating races where 3 horses qualify. It's only happened 2 or 3 times in the six months.

Good going. Yeah, I think if you deleted those that hadn't won at the distance, your overall strike rate would probably improve. The only thing is whether you would delete any really good priced winners by doing that.

Sportz or Jacfin.....do either of you have a LINK ADDRESS for the unitab ratings? I've had a bit of a look around but can't seem to find it. :???: And, do you need to be a registered member or anything to gain access?

Also, on the distance thing...what about horses that won or PLACED at the distance OR won or PLACED within 100m (+ or -) of todays race distance? I know it's a bit harder to research but it might grab those selections eliminated by the strictly c or d rule?

Michael,

Totally free and VERY easy to use:
http://www.tabonline.com.au/default.stm

Simply click on Racing, then click on the race you want and the ratings are on the right side of the screen. :smile:

It is pretty time consuming to check past results because each race has to accessed.
If we are thinking of checking each weekday perhaps we could have some volunteers and split the load.

Michael, I started checking my first-up system and I soon came to the conclusion that your idea would produce many more bets but not a lot more winners. I think if we stick simply to Distance winners, we should do okay. Alternatively, we could be very patient and just wait for the 'specials'. 9 wins from 13 bets looks promising!

Kenchar, thanks a lot for asking about those first-up strike rates. :smile:


[ This Message was edited by: sportznut on 2004-03-02 14:04 ]

Thanks for the link Sportz and sorry about the distance suggestion but it was just a thought (and not much good either it would seem).

That's okay, there's absolutely nothing wrong with making suggestions and offering opinions. :smile:

Sportz,
I found 1 bet today which won well but too short for me, do you agree????

Cheers

Are you talking about Strictly Fast??? It wasn't actually a selection because there were TWO horses in the race with 100pts. To be a selection, the horse must be the ONLY 100 rater in the field after scratchings.

By the way, that other 100 rater ran 2nd. There were also two 100 raters in Race 7 and they ran the quinella as well.


[ This Message was edited by: sportznut on 2004-03-02 18:50 ]

Shaun,
I've researched another 2 months results and while the results have still been pretty good, they haven't been quite as good as the last 3 months. I'll keep looking a bit longer to see if I can find a definite pattern. At the moment I think metro racing might work best. What do you think is a reasonable period of time to test something like this, 6 months? 12 months??? By the way, in my original 3 month test, even betting on ALL sole 100 raters first up showed a profit, only around 20% but still a profit. While I haven't kept track of those figures, I think that trend has continued.

Jacfin,
While I was going through the results, I kept noticing all the good priced winners from the 100 raters 7 days a week, and I think you really could be onto something with your idea. :smile:


[ This Message was edited by: sportznut on 2004-03-03 09:38 ]

Sportz i use this method when testing races because i don't have a data base....can't remeber who posted it they deserve credit for it

1. First sample = 150 recent races (or bets) If this shows miserable results, forget it. If it gets near to break even or pays POT continue. This sample will include at least one period of three consequitive days.

2. Second sample = 100 races from the same season in previous years (not recent races) but with NO consequitive days. If its near to break even or in POT, continue.

3. Third sample = 100 random races from all seasons trying only one or two races per day from here and there. If its near to break even or in POT, continue. A system MUST pass this test. (If you only sample consequitive days you can hit distorting cycles and mini-cycles. You have to sample against this phenomenon.)

4. Fourth Sample = carefully tabulate results over the last week's races, going back over some days covered in sample 1 but writing it up on a spreadsheet to examine results more closely.

i have tested jacfin system before and the recent results are good the past results are not so good....the only thing i can say to this is that the ratings have changed in recent times and are much better than before here are some results with out going in to to much information

That system testing idea is a bit strange, but I guess it would work. Anyway, I've compiled my first-up system results back to Sep15 and this is what I've got so far:

Selections 102
Wins 32, Win return $167.10, Win profit 64%
Places 59, Place return $115.20, Place profit 13%


[ This Message was edited by: sportznut on 2004-03-03 11:43 ]

Yeah, I really think there is merit in Jacfin's idea and I do agree that I think the ratings have probably improved in recent times. I'm currently working on a few things using these ratings and considering they're free, I think they work very well indeed.

sportznut
when you have checked back results did you notice if any 100 pointers were racing at their home track ?
cya

No sorry, I didn't make any note of that.

Shaun
Bear in mind that my rules apply only to Sat city meetings excluding Adelaide. Your results for Sat seem to include all meetings.
I've tested back to August last year and the LS profit is 86 units. Aug was a losing month with Bris contributing 7 losers straight. Interestingly, working backwards in the testing Bris has had 1 winner at $11 in the last 31 races. The recent Bris results have been the best - perhaps they have improved or maybe it's seasonal.
On the testing issue I find a good method to cover all seasons is to test the first Sat in each month for the last 12 months to get an idea of viability. Maybe the first week in each month if testing a daily system.

Jacfin....my test on saturday are for the 5 states city meetings on midweek races it covers all Australin races.....i do like the results not to bad and saturday does out perform midweek

Jacfin,
I've been going through the results and I reckon $6+ would do okay. I've seen quite a few winners in the $6-$8 range.

Sportz
As I continue my research I'll take note of the $6+ as well as the $8.5+ and report back.
I have noticed winners in all ranges and this could well be the basis for a different system.
I've always liked longshot methods but the ratings do seem like fertile ground for all sorts of ideas.

You're not wrong!!!

From today's racing, Bris 5-1 Chinbok, the only 100 rater in the race wins at $13 and Murray Bridge 4-2 Cosipura, again the only 100 rater, wins at $7.70. A few other shorter priced winners as well. :smile:

[ This Message was edited by: sportznut on 2004-03-03 17:11 ]

I've just completed another month and the results were good ( but not for Bris )
16 selns - 3 winners - return $34 - LS profit = $18.
Sportz
Would you mind emailing me at jacfin@mail.nu if convenient plse.

Sure thing! :smile:

The results of your little system seem to be holding up very well. How many months is it now that you've looked at?


[ This Message was edited by: sportznut on 2004-03-03 17:28 ]

I've looked at Feb 04 back to July 03 inclusive.
I'll go back to Mar 03 so that I've got the full year.

hey guys...i have looked at the $6+ rabge and yes they do come in but that also gives you more loseing selections $8+ is a good starting point
