My cousin is a sports nut, and a punter. Also a programming gun. This isn't supposed to be a plug for his site, but a tool for people that love a bet on the horses.
He has a website, http://www.puntingform.com.au which is great for hunting market mismatches, and for trying to find overs.
http://www.puntingform.com.au/odds-comparison/
He also has functionality to subscribe to winning systems, or create your own systems using drivers like recent starts, preparations, classes, distances, tracks, trainers, jockeys, ratings, sectionals etc.
I haven't actually subscribed to anything on it but it might be of interest to some.
I'm more of a sports punter. In regard to keeping records, completely agree, I have gone much better once I started holding myself accountable.
The problem, in my opinion, with any sort of system, is that it assumes you, and everybody else can consistently beat the bookies using it. If that was true every bookie would be broke. Bookies also have dozens of people whose sole job is to set odds, and if they wanted to they could also utilise these sorts of systems too or at least develop counter strategies to them
I agree. And have a financial risk analysis background so I'm aware of various modelling that would be done. And a good thing is only a good thing for so long, but a dollar can be made in short term trends.
That site isn't any one particular system. There are hundreds of different systems on there.
It is a create your own sort of environment.
I know on bloke that likes punting horses that have had 2 fourth places. You could add a criteria that last up it was a dead 4 (or whatever) and it is down a grade. And it will test this theory on past data to work out if it has been a common occurrence etc.
I don't use it because I don't follow horses close enough, but might be of use to some.
