Hi Bret, and welcome.

I have followed a path of ratings for years along with other ideas i though would be able to run but always came back to my ratings.
I used to have a big issue with pricing a market from my ratings and it took a few years and some help to get it right, i used to dutch bet but found betting each selection as an individual selection works best for me, i bet 4 runners a and as long as the average divi and the strike rate of each runner is in a positive position i am fine with that.
