Track Constants for Speed Handicapper® v5.0
Track
Constants! First defined by Charles Carroll in the
book Handicapping Speed, after years of development
can now be applied to almost every distance at every track
in North America using Speed Handicapper® v5.0!
Tracks
have certain physical characteristics that affect the times
that are recorded on them, ranging from one-jump flying starts,
to extremes such as the downhill Santa Anita "about"
6.5f course, which is the most extreme example in North American
racing. These "Constants" were originally described
by Charles Carroll in the book Handicapping Speedbut,
short of visiting every course with an engineer's transit,
there seemed to be no solutionuntil Carroll finally
cracked the problem in 2005. Now the Track Constants are updated
annually.
Track
Constants
are calculated using a proprietary method, based on running
times at North American tracks from the previous year. The
2008 Constants includes all polysurfaces running in 2007.
As new polysurfaces come on line and if times change significantly,
as occurred at Del Mar during 2007, midyear updates are provided
free of charge when the data is valid enough to make changes.
