I use all the years available. I always look at the qualified horses, and try an gauge from the final positions in relationship with their odds. Watch out if there are horses that have won more than 1race in the parameters, it kinda skews the reports. The more the variety of winners the better. As well as that look out for results that have more than 1 qualifier and to see how they preformed
