I am assuming users of this site will be concerned with Speed Figures at two levels.
Most will be happy to know how the numbers compare to other common speed figures, but some
may have a more technical bent and want to know in more detail how these numbers are calculated.
I will address the less techmical answer first, then later get into more detail.
Most users will have heard of Beyer's and BRIS speed numbers among many others.
Our numbers are similar to, but different from, all of those. First ours are 'anchored'
at 90, meaning the classic 10K Claimers (older males) win at about 90. Beyers (I believe)
are anchored closer to 80, and the BRIS numbers seem to be about 85.
Differences from this speed are given more or fewer points depending on the distance.
Our numbers adjust upto 2 points per length for races of 5 furlongs and shorter, down to 1 point per length
for distances beyond 10 furlongs.
Beyers are adjusted about 3 points per length for short distances, and about 1.5 for very long
races. BRIS numbers use a Beaten length adjustment between 2 points per length for 6 furlongs
and down to 1 point per length for intermediate routes.
As a result of these differences you can not make direct translations of one speed figure type to another, but they
all give about the same type of numbers.
Another important, but technical, difference between Beyers and our figures, is that Beyers are based on a projection
system where each race is compared to the expected speed of that race considering its entrants, while ours
primarily rely on Class Pars to project Track Variant adjustments.
Note: the Speed Ratings in the DRF are a different item altogether, and not to be confused with real speed figures.
