BRIS Speed Ratings are based on a variation of the "projection method" which some other popular speed figures are based. Unlike others, BRIS uses an objective, computer precise method to make the final time projections rather than using the subjective opinion of one handicapper. The past performances of every horse competing in a given field is examined with the painstaking detail only a computer can do. The projections generated by Bloodstock Research's computer system are based on proprietary techniques and algorithms which have been rigorously tested and long proven over hundreds of thousands of races. This computer precision enables the BRIS Speed Ratings to use the most accurate projections and variants possible.
