As requested by Lenny here is the system i sent into p.p.m. that appeared in their may 91 magazine,it's fairly simple to use and is based on the Sportsman's zip rating but could be used with any reliable ratings.

(1)Use the Sportsman form guide,note the Zipform rating for each horse in the race.

(2)Add each horse's win% to the Zipform figure.

(3)Add 10 points if the horse is trained by one of the states top 5 trainers.

(4)Add 5 points if the horse is to be ridden by one of the states top 5 jockeys.

(5)The horse with the highest total is the selection.

(6)Do not bet on 2yo or maiden races.

(7)A horse must have at least 4 starts to qualify and not be unbeaten.

Some suggestions for improvement;

Make up your own list of jockeys and trainers.

Convert the pre post odds into a % and add that to the final figure.

Ignore jockeys and trainers and add an X factor like kgs under top weight to give the system a chance to produce a surprise result.

Work out which races make the most money and if races with less than say 10 runners dont turn a profit ignore them,look at Q's and T's in races with 10 or more runners.
