f How Speed Ratings Are Compiled Speed ratings appearing in DAILY RACING FORM past performances are based on a comparison of each horses running time with the track record. The track record will receive a standard rating of 100 — thus, a horse equaling the record will have a speed rating of 100. For each one-fifth second, slower than the track record, one point is deducted. Therefore, the rating for a horse running his race two and one-fifth seconds slower than the track record receives a speed rating of 89 100 minus 11. EXAMPLE Track record 1:10 Winners time 1:10!and .Time of second horse 1:102s Time of third horse 1:11 Time of fourth horse 1:11% Time of fifth horse 1:114,6 Rating figure 100 - * Rating 99 97 - 95 93 91 One point the equivalent of one-fifth second is deducted from the rating for each length the horse is beaten. Thus, a horse beaten four lengths in a six-furlong race run in 1:11 rating of 100 where the track record is 1:10 is timed in 1:1116, receiving a speed rating of 91. Where a horse breaks the track record, his speed rating will exceed the standard rating of 100 by one point for each one-fifth second faster than the track record. Thus, if the record Is 1:10 and a horse is timed In 1:09%, his speed rating will be 102. The new record then becomes the, standard 100.
