Last week, we used DRF Formulator to come up with some plays who ran well and, maybe even more importantly, a couple of short-priced horses who we thought might be vulnerable and proved to be, most notably Untapable losing at odds of 1-10. Formulator allows you to see the lifetime past performances of horses who have run in the past five years for any trainer who has horses entered, as well as charts, replays, filters, and more. With access to this database and with one-click access to replays, it can allow you to see some things that aren’t readily available to the betting public. Using Formulator, let’s look at some specific horses entered at a few different tracks Saturday.
