RAS Rankings are not simply a list of horses ranked by their peak rating - which explains why things can look slightly out of order alongside the rating provided above - but instead look to consider horse's records more broadly and rank them by a score derived on more than just one performance. The score on which the horses are ranked is greatly influenced by peak performance but also other runs and ratings within the horse's profile. A time decay function and momentum factor look to keep the rankings current and answer the question - who is the best horse in the world right now!
