The Daily Double! GRASP and GSV
[Updated February 22, 2009]
GRASP: A Must
for Breeders, Buyers and those who Breed-To-Race
- GRASP: The BEST Tool for Measuring ACTUAL Genetic Strength of a
- GSV: A tool for PREDICTING
the Genetic Strength of a Thoroughbred.
The GSV score is the average of the Male and Female half GSV scores. This
Matchmaker tool has been especially designed for all track
surfaces. It is easy to use by all involved in the thoroughbred
business. Updated stats on GSV
ranges of over 33,000 horses in the GSV databank can be found at the
bottom of this page.
This information will give you a much better idea of how a GSV number
compares to other GSV numbers by location, class and type. The GSV
includes all horses within 5 generations: sires and mares in the 2009
- GSV2: The
GSV2 is also hypothetical score,
not necessarily reflecting the actual genetic ability of a particular
individual. The GSV2 is the GSV score plus the UP score [up to a
maximum of 5.00 points. It is commonly used in broodmare
- UP: The
UP score measures whether the GSV is higher [a positive number]
or lower [a negative number] than the average GSV score produced by
that sire. Since the sire's half of the pedigree stays the same,
the more Genetic Strength in the female half, the more positive the UP
Score. An UP Score of 0.00 indicates that the sire appears only
once in the databank and hence no average sire value.
GSV: "A Must
for Handicappers, Stud Farms, Owners and Breeders"
males & females within 5 generations,
pedigree construction, tail-female line strength, etc.
individual racing brilliance, class, earnings,
blacktype events, speed vs stamina, type, etc.
Performance: Measures success
as a sire or broodmare, %
of runners, winners, SW's, 2yo winners, Average Winning Distance, etc.
UP: How the
GSV score compares to the average GSV score produced by that sire
The GSV predicts
thoroughbred performance before the foal is
born based on
the Genetic, Racing Ability and Stud Performance
(GRASP) of all horses in its 5 generation pedigree. Prior to 2009, the
GSV omitted the first five dams in tail-female line, which made
it a great tool to be used with a sales catalog page as the GSV
rest. The GSV can change according to the recent stud performance
of individuals in its pedigree and is updated yearly.
breeding and handicapping tool has been added to my GSV
numbers. I now generate an UP score based on how the GSV number
of a horse or hypothetical foal compares to the average GSV number
of a sire's average foal. An UP score of +2.00 indicates the
generated GSV number is 2 points higher than GSV average by that sire.

Understanding the GSV and GSV2
Do you believe that the pedigree of a thoroughbred can be an
indication of it's potential?
If you answer "NO ", then the GSV/GSV2
you. Thank you for your interest.
If you answer "YES",
then you will be
able to use the GSV & GSV2 to
help you. Keep reading to learn all about
the GSV & GSV2.
The answers to your questions about the GSV & GSV2 that
to this page should be found below or linked to this page.
GSV & GSV2 are
numerical scores developed by George William Smith, known for
his pedigree analysis skills that led to two Eclipse Champions,
Farda Amiga and Vindication; European Horse of the Year, St. Jovite;
and connected to hundreds of stakewinners.
Throughout my career I have constantly been asked about the strength of
pedigrees. Clients ask if they should purchase or sell a certain
horse, breed this mare to that stallion to produce a certain type of
foal, etc. I usually answer that I need to take an in-depth look
at the pedigree, race record and stud performance so that I might be as
accurate as possible about the potentials of the pedigrees
For over 25 years I have been generating a score for their thoroughbred
so that my clients may more easily be made aware of the strength of the
throughbred I am researching for them compared to other
thoroughbreds. It is called my GRASP score. GRASP stands for Genetic, Racing Ability and Stud Performance.
The Genetic score
arrives with the foal at birth, but may change throughout its lifetime
as its parents and 5 generations of ancestors do better or worse at
stud as time goes by. The change can be dramatic if both parents
are in the early stages of their stud career or slight if both have
been in the stud a long time. Usually, the foal can not do a thing
about it's Genetic score, but if
the foal is very, very good it might have some impact on the stud
career of its parents.
The Racing Ability score is earned during it's
racing career and once retired does not change. The Racing Ability
score can help you understand you whether the horse got its fair share
of the good genes or not. If a horse has a high Genetic score but cannot outrun a fat
man, the Racing Ability
score will reflect that it did not get much of the 'good stuff' from
its parents. On the other hand, if the foal has a high Genetic score and runs like the wind,
the Racing Ability score added to the Genetic score will be very
high, predicting that there is much potential in this horse when sent
to stud. Thus, I use the GRA
score as a guide on how much potential there is in the horse before it
produces a foal. I always publish the GRA scores of potential stallions so
that my clients know ahead of time who I predict will succeed and who
are likely to fail.
The Stud Performance
score is earned during the stud career of the horse and until it no
longer has foals from its producing daughters racing on the
track. Depending on how many foals and the length the horse stood
at stud, this score often changes even after the death of the
horse. The older a horse is or would have been, the less this
The GSV & GSV2
are derived from the GRASP
scores of the 31 thoroughbred sires found within 5 generations and
weighted according to how close up they appear, but is not male
dependent like dosage, etc. The GSV
actually measures the Genetic Strength of 57 of the 62 horses within
those 31 sires, beginning with the sire of the horse and the next four
generations. The horses currently not measured are the 5 dams
tail-female line and these can be found on a catalog page. The GSV & GSV2 is a
perfect supplement to
catalog page of a horse for sale as the GSV & GSV2
objectively measures the
genetic strength of the horse, whereas a catalog page is highly biased
toward the best ancestors in a
horse's tail-female line pedigree.
The Daily Double: GRASP and the GSV
databank has over 400 fields of data, of which some are not
weighted or weighted according their apparent benefit in
producing better thoroughbreds while racing and/or later in the
stud. The GRASP score is earned
by actual performance.
My GRASP databank now generates two scores, which I call GRASP1 and
My GRASP1 score is used when the stallion appears through a son and my
GRASP2 score is used when he appears through a daughter. The
GSV/GSV2 is now role
GSV stands for Genetic Strength Value. It is based on five
generations of GRASP1 or GRASP2 scores. It is a hypothetical
score. The horse does not earn its GSV score. It is the
score that an average hypothetical mating between a stallion and a
broodmare generates. The actual horse might be far better or
worse than what the GSV score indicates depending on the combinations
of genetic material actually received in the mating. The GSV2 now
includes a small compatibility factor called the UP score. If the
GSV score is 65.00 and the UP score is 2.00, the GSV2 score is
67.00. Note: The UP score has a maximum positive score of
5.00. Minus scores are not subtracted from the GSV to get the
GSV2 score. In the above example, if the UP score is -3.12, the
GSV2 score is still 65.00.
The GSV scores are calculated by adding the GRASP scores of each
generation and getting an average for each generation
for the male half of the pedigree and then doing the same for the
female half of the pedigree. I
then average the male and female scores to get
the GSV score. By calculating both halves of the
pedigree separately, using both sires and mares, the GSV of 2009 is
more reliable than the old GSV
score, which used to be calculated by averaging each generation
separately, thus giving the sire of the horse more weight as it is the
only sire in the first generation.
Through February, 2000, the GSV is proving reliable as a
handicapping and breeding tool.
1. You have to think of the GSV & GSV2 as a
2. It only measures the genetic
strengths of a 5 generation pedigree.
3. Think of it as the sperm is still in the stallion, the egg in
4. The GSV & GSV2
theoretically combines them, but just as two bays may
produce a chestnut what is wishful thinking
may not happen. The foal may get a
certain set of genes and its full
brother might have received a lot of different ones. But the GSV & GSV2 score will be the same for both. It
is a theoretical score.
a. The GSV & GSV2 score
is produced before the
birth of the foal, but may change as the stud performance within 5
b. A yearling with a high GSV & GSV2 and
legs that go in
each direction should be ignored.
c. A yearling with a low GSV & GSV2 and
correct legs with a
balanced individual may be a good buy.
d. A yearling with a high GSV & GSV2,
correct and a good
walk should never be ignored.
5. Once the foal hits the ground, the foal begins to accumulate
points toward its own GRASP score. Thus, full brothers may have
radically different GRASP scores
achieved in their lifetime and thus generate entirely different GSV & GSV2 scores
for their foals.
6. Only GRASP values are handed down to the next generation,
never the GSV & GSV2!
So what is
the value to
you of the GSV & GSV2?
It allows you to make better
decisions using hypothetical matings, etc., all other
things being equal, in choosing the right broodmare, stallion for your
mare, weanling, yearling and 2YO's-in-training sales, along with
normal conformation checks, etc.
The GSV & GSV2 is
showing good value as a
regardless of the class of field or race track. However, using
Graded/Group Stakes and Stakes at major world-wide tracks may yield the
most value. A
validation study that was done on the GSV2 that showed the higher the GSV & GSV2, the
greater the likelihood of a better stakewinner. This study used
over 10,000 thoroughbreds and
from throughout the world.
stats on GSV ranges of 18,043 horses in the GSV databank thru January
Of the 18,043 horses in the
databank: ~3000 are fully researched good sires from all areas of the
world born after 1875; ~2000 horses that have raced in at least one
graded/group race; ~ 1000 maidens that raced in Great Britain; ~2000
horses that raced in England; Ireland, France, Germany, South Africa,
South America, Japan, Hong Kong, New Zealand and Australia; and ~8000
horses that have raced in North America at the major tracks in Southern
California, KY and New York, but not in Group/Graded races; and ~2000
that raced at the minor tracks.
1. The average score of all thoroughbreds in my GSV databank is 68.01.
Clearly, from looking at the stats above, the GSV databank is skewed to
horses that race in better class company and at major tracks. It
is important to know where a horse is racing and in what company to
fully understand how a particular GSV score measures up.
2. The median score of all thoroughbreds in my GSV databank is 68.12.
3. The GSV average of horses at minor tracks racing around the world
~61. Those that don't get to the races throughout the world average
around ~59. The GSV average of horse racing at the better
meetings in South America is ~ 63 and throughout the rest of the world
is ~65. Those that race in Group/Graded races average ~70 on all
surfaces. Those that race in Graded/Group Races on turf average
