Definition of Pace
Slope is a measure of
fatigue. It parallels the increase in time required to negotiate an
additional distance. The higher the number, the steeper the slope,
indicating that the fatigue rate is greater. Slopes will generally fall
between 0.9 (slow early-fast late) and 1.2 (fast early-slow late).
Intercept is a measure of early speed and is inversely related to the slope.
In this case, the lower the intercept, the greater the relative early speed.
Intercepts also will usually fall between 0.9 (fast early) and 1.2 (slow early).
Correlation Coefficient is a measure of how efficiently a horse's speed
is used throughout the whole race. Perfect efficiency is equal to a CC of
1.00000. Any value below 1.00000 represents less than ideal efficiency,
although it is almost always greater than 0.99900. The very best horses
continually display CCs above 0.99990 while lower quality horses may not
display CCs that high.
remaining terms are part of the "Sartin Methodology" for describing
pace characteristics as discussed by Tom Brohamer ("Modern Pace
Handicapping", by Tom Brohamer, William Morrow and Company, Inc,. New York,
(Early Pace) is
velocity in fps (feet-per-second) to the second call.
is the average of early pace and the final fraction, thus relating a horse's
speed to the second call and his ability to finish.
(Average Pace) is the
average of EP and SP.
(First Fraction), 2Fr
(Second Fraction) and 3Fr (Third Fraction) are the average velocities in
fps between each of the calls.
(Total Energy) is
the sum of EP and 3Fr. It is the total available energy based on current
conditions of distance, surface and track as well as inherent ability.
(Percent Early) is
a relative measure of energy used through the second call (EP/TE). Speed
types display %E figures significantly higher than off-the-pace types, although
the absolute numbers are greatly affected by the distance of a race.
