MixMaker is only available to monthly subscribers. Give MixMaker race results from previous races, and using sophisticated artificial intelligence, it will try to create a Mix that would have accurately predicted the race. Once you know the proper settings to handicap that type of race - you can save them and apply them to future races. For example, if you were to select a 6f Claiming Race at Keeneland that ran yesterday, you would be able to input the top 3 finishers into the program, hit the "Run Mix Maker" button, and then see the settings needed to predict that result. Save those settings as "Keeneland 6f Claiming", and the apply them to the next race that meets those conditions!
