With handicap ratings it’s easy to go with what you already believe. But with speed ratings, the method of comparing race with race rather than horse with horse often flags up errors in your thinking.

This looks to be the case with the Darley Irish Oaks where I was expecting to award a relatively low speed rating to the winner, in line with those I’ve been awarding for most British and Irish Group 1’s for three-year-old fillies up until now.
