WHAT DO THE BRISNET PACE RATINGS MEASURE?

Brisnet Pace Ratings measure how fast a horse ran up to a specific point-of-call 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 quarter-mile call. (2f)

4f Pace Rating – rates how fast the horse ran from the start to the half-mile call. (4f)

6f Pace Rating – rates how fast the horse ran from the start to the three-quarter 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 BRISNET 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 BRISNET PACE RATINGS CALCULATED?

Brisnet uses proprietary techniques and algorithms which have been rigorously tested and long proven over hundreds of thousands of races to accurately compute the Brisnet Pace variants and ratings.

WHAT ARE THE FUNDAMENTAL DIFFERENCES BETWEEN THE BRISNET PACE RATINGS AND THE BRISNET SPEED RATINGS?

Unlike the Brisnet Speed Ratings, which employ a differing points-per-length scale depending on the race distance, the Brisnet Pace Ratings use a fixed scale of 2-points-per-length for all pace calls 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 is the same. That is, a quarter-mile call is equal to two furlongs regardless of whether the entire race is six furlongs or 10 furlongs (1 1/4 miles). Since the pace calls being measured are equivalent across differing distances (a half-mile call in a sprint is the same distance as a half-mile call in a route), the Brisnet Pace Ratings use the same 2-points-per-length scaling for all pace calls across all distances.

HOW CAN I CALCULATE “TURN TIME” USING THE BRISNET 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:BRISPACE TURN
 E1E2( E2 – E1 )TIME
HORSE “A”9096( 96 – 90)= +6
HORSE “B”9296( 96 – 92)= +4
HORSE “C”9696( 96 – 96)= +0
HORSE “D”100100(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 horses “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 Horse “C” (E2= 96). Therefore, Horse “C” and Horse “D” ran the same speed between the first two calls.
