BRIS PACE RATINGS F.A.Q.

WHAT DO THE BRIS PACE RATINGS MEASURE ?
BRIS Pace Ratings measure how fast a horse ran up to a specific point-of-call (2f,4f,6f,...) in a race - the higher the number, the faster the horse ran.
      2f Pace Rating   - rates how fast the horse ran from the start
                         to the 1/4 mile call. (2f)

      4f Pace Rating   - rates how fast the horse ran from the start
                         to the 1/2 mile call. (4f)

      6f Pace Rating   - rates how fast the horse ran from the start 
                         to the 3/4 mile call. (6f)

      E1 Pace Rating   - rates how fast the horse ran from the start
                         to the 1st call (2f Pace in sprints, 4f Pace
                         in most routes).

      E2 Pace Rating   - rates how fast the horse ran from the start
                         to the 2nd call (4f Pace in sprints, 6f Pace
                         in most routes).

       Late Pace Rating - rates how fast the horse ran from the 2nd call
                         (pre-stretch call) to the finish.

ARE BRIS PACE RATINGS COMPARABLE ACROSS DIFFERENT TRACKS ?
Yes. Since the ratings are "fully adjusted" ( reflecting both daily and track-to-track variants), they are comparable across all North American racetracks.

HOW ARE THE BRIS PACE RATINGS CALCULATED ?
Bloodstock Research uses proprietary techniques and algorithms which have been rigorously tested and long proven over hundreds of thousands of races to accurately compute the BRIS Pace variants and ratings.

WHAT ARE THE FUNDAMENTAL DIFFERENCES BETWEEN THE BRIS PACE RATINGS AND THE BRIS SPEED RATINGS ?
Unlike the BRIS Speed Ratings which employ a differing points-per-length scale depending on the race distance, the BRIS Pace Ratings use a fixed scale of 2-points-per-length for all pace calls (2f,4f, etc.) - regardless of the race distance. The fixed 2-points-per-length scale is based on the fact that, regardless of the entire race's distance, the ground covered for any given pace call (2f,4f,etc.) is the same - that is, a 1/4 mile call is equal to two furlongs regardless of whether the entire race is six furlongs or ten furlongs (1 1/4 miles). Since the pace calls being measured are equivalent across differing distances ( a 1/2 mile call in a sprint is the same distance as a 1/2 mile call in a route), the BRIS Pace Ratings use the same 2-points-per-length scaling for all pace calls across all distances.

WHAT ARE THE FUNDAMENTAL DIFFERENCES BETWEEN THE BRIS PACE RATINGS AND "QUIRIN" STYLE PACE RATINGS ?
Quirin style pace ratings are based around $10,000 3up Open male Claiming pacesetters being equal to 100 across all distances - the BRIS Pace Ratings are not. Sprinters run faster than route horses in the early going of the race and the BRIS Pace Ratings reflect that reality.

When a sprinter stretches out or a route horse shortens up, Quirin style pace ratings systematically underates the demonstrated early speed of all sprinters and overates the demonstrated early speed of all routers.

To accurately measure the demonstrated early speed of any horse at any distance, the BRIS Pace Ratings reflect exactly how fast the horse ran - regardless of race distance. Therefore, unlike Quirin style pace ratings, a horse who ran an adjusted time of :45 flat for the 1/2 in a 6 furlong sprint earns the same 4f pace rating as a horse who ran an adjusted time of :45 flat for the 1/2 in a 1 1/16 mile race.

HOW CAN I CALCULATE "TURN TIME" USING THE BRIS PACE RATINGS ?
It's easy! Simply subtract the 1st call Pace Rating (2f Pace Rating for sprints, 4f Pace Rating for most routes) from the 2nd call Pace Rating (4f Pace Rating for sprints, 6f for most routes):

      BRIS Turn Time          = E2 Pace Rating - E1 Pace Rating
   or
      BRIS Turn Time (sprint) = 4f Pace Rating - 2f Pace Rating
   or
      BRIS Turn Time (route)  = 6f Pace Rating - 4f Pace Rating


   For example:
                 BRIS PACE                  TURN
                  E1   E2      ( E2 - E1 )  TIME
   HORSE "A"      90   96      ( 96 -  90) = +6
   HORSE "B"      92   96      ( 96 -  92) = +4
   HORSE "C"      96   96      ( 96 -  96) = +0
   HORSE "D"     100  100      (100 - 100) = +0
Horse "A" has the fastest turn time (+6) which is one length (2 points) faster than Horse "B" (+4).

Also, note that HORSE "C" & "D" have the same turn time (+0). Horse "D" (E1=100) ran 2 lengths (4 points) faster up to the 1st call than Horse "C" (E1= 96) but Horse "D" (E2=100) was still 2 lengths faster up to the 2nd call than than Horse "C" (E2= 96). Therefore, Horse "C" and Horse "D" ran the same speed between the first two calls.
