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 1 his race two and one-fifth seconds slower than the track record receives a speed j rating of 89 100 minus 11. j EXAMPLE I Track record 1:10 Rating figure 100 j " Winners time 1:10 V£ Rating 99 - Time of second horse 1:109 97 Time of third horse 1:11 95 Time of fourth horse 1:11 rS 93 Time of fifth horse 1:114s 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 -1:1156. receiving a speed rating of 91. v 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. . .
