Data analyst for racing prediction formula

I have got the statistics for 56 races and I also have the details of the winner in each race. I need somebody who can take a good look at the information for each race and identify a pattern for the winner of each race. I currently have a pattern in place which is accurate for 40% of winners. I need a freelancer who is able to improve the accuracy. *** PAYMENT WILL ONLY BE MADE UPON EVIDANCE THAT YOU HAVE IMPROVED THE ACCURACY *** A sample is attached for you to look at which just shows 5 races. If I think you are the best person for the job I will send over large file with data of 56 race for your to analyze.
