Welcome to a new free feature on the site:

Ratings for all TAB races every day posted as a free download.

They are produced using a machine-learning ensemble approach, that is the use of 25 separate models to come up with a single, overall prediction. The model uses over 40 variables related to runner-specific factors, race-specific factors and track-specific factors. The model is retrained on a weekly basis to ensure it keeps up with any trends or changes in racing.

We’re expecting people to use them in very different ways, but here are a few pointers:

Rank    SR
1          28%
2          17%
3          14%
4          11%

Quinella in top 4 rated: 40%
Trifecta in top 4 rated: 21%
Top rated loses approximately 3% at Best Tote.

  • Races with unraced runners are excluded
  • Races with a clear spread in the ratings (ie 1 or 2 horses well clear of the rest) can have some good value.
  • The rated prices are there as a guide and not there to be bet as strict overlays, if a horse is rated well clear of the rest (i.e. 20 pts clear) and it is rated $2.80 but the market is trading at $2.70 don’t be afraid to back it because it is under the rated price. In the same way if the market is trading at $1.60 that’s probably too short to have a bet on.
  • Overlays are best used for metro racing and to be more specific the higher class metro races (i.e. stakes races).
  • There are no real trends in distance ranges other than a higher degree of accuracy for races 2300m+.
  • The ratings don’t include variables related to the run the horse will get, e.g. the model won’t know that a horse will map to get caught 3 wide and also obviously there is no information contained about any track bias/patterns that presents itself on the day.
  • Our in-house analysts such as Nathan Snow, Trevor Lawson or Adam Mintz do not use these ratings as the basis for their form study. They go about things their own way and get to know every horse, jockey and trainer as individuals. These ratings were developed externally by a data scientist rather than a form analyst.

Post a comment below if you have any questions at all about how they are generated or how you might use them.

Good luck!

  1. I am betting on most race meetings in Victoria at the moment and find I have a lot more success betting on country races. I have been betting on favourites and throwing in 3 or 4 each way bets as savers but found that there are a lot of false favourites. I am a $20 win and a $10 each way bettor at the moment and might bet more as my bank grows. I have had a lot of success following regular winning trainers such as Weir, Hayes Tabernig, A & M Payne, Freedmans, Maher, and jockies: Williams, M. Payne, Meech, Currie.
    Childs, Rawiller, Hill, and Allen when riding for Weir.
    I keep a document on each individual meeting of every race. I note the name of the winning horse, jockey, trainer, barrier number, last start distance compared to the current race distance, lengths beaten or won by in last 2 races, class, tote price and speed pattern. There is definitely a pattern in winning barrier numbers and horses that race on pace. Tab and Race Caller tipsters are pretty spot-on lately. Happy punting everybody!

        • Thanks Dave I finally have sorted things out and enjoy the free Data Base Ratings every day which can be a bit hectic psychologically trying to concentrate on punting and carrying out every day tasks. Have had some great wins including the first at Wangaratta today, unfortunately not your Data Base Rating. Call it intuition but had two other bets on that race before I downloaded your ratings (never enough hours in a day). One win bet on the favourite and an each way bet as a saver. There have been some big dividends come up from winners on the limit weight lately in country Victoria so I had a quick look at #13 WILSTON (4) ridden by a top provincial jockey Jarrod Fry and trained by Silvia Thompson a well known winner of provincial country races. The comments from the TAB website said: In Weaker Class FS(-5.5). Blinkers on. Last run was 15th 12L, Hard Go Jo at Wagga (CL1) 1600m. On Nov 9 slowly away when 8th 9.5L, Atlantic Express at Bendigo (3Y+Maiden) 1400m. Each way claims. Somebody must have known something and the each way comment was encouraging so I threw on $10 each way and low and behold it came home and paid $20.20 and $4.80, a huge reversal of previous form, it seems in many cases that putting blinkers on a horse improves the horse’s ability to win. Had a great day today thanks to the ratings, Starting to get some of my money that the TAB have take off me. As I build up my bank (hopefully) I will take out a subscription to your tipping services. Keep up the good work, not many freebies in the tough world of the thoroughbred horse racing game.

  2. Can anybody explain why the shortened TAB tote price from your rated price. Was this final TAB Tote price because of the popularity of the trainer or was it because of favoritism?

    In a parimutuel system like the Tote the dividend just reflects the amount of money invested on the horse;
    Dividend declared on Neddy = (Total of all bets minus takeout)/Amount bet on Neddy
    Dividends are rounded down to nearest 10 cents,takeout is usually close to 18%

    In the case you mention the Weir stable are known to like a decent bet so stable support would be a factor. Another factor could be recommendations from media tipsters (print, radio, tv, internet).

    A rated price like Champ’s reflects their assessment of the chance of the horse relevant to others in the race at some time before the race. The rating may not be able to include late information like stable support, incidents on the way to the course, horse off its feed, jockey having issues etc etc and also the rated price may not allow for these effects on other runners in the race.
