First, there was my GRASP
program. It was designed to accurately assess what was
under-the-hood of a thoroughbred'. My GRASP program is the result
of over 30 years of pedigree analysis research. GRASP was
developed as a tool to help breeders and owners. GRASP stands for
(G)enetics, (R)acing (A)bility and (S)tud (P)erformance.
Second, I used my GRASP
program to generate the GSV (Genetic Strength Value). The GSV
measures the hypothetical genetic strength of a thoroughbred. The
GRASP program generates what is and the GSV generates what might
be. The GSV has both application in breeding and betting.
It is very useful to breeders in predicting the potential of the foals
they breed. It is especially useful to handicappers in predicting
the racing ability of thoroughbreds in Maiden Special Weight and Graded
Stakes.
Third, Using the GSV scores I
generated when producing my GSV race cards for North America, I have
now developed a new means for
measuring the book of a stallion. For all runners of a stallion,
I have computed an average Dam GSV score. Since only the dam's
half of the pedigree is used, the score will reflect the book of a
stallion as expressed in a GSV score. I call this my MSB score or Measurement of a Stallion Book. This can be a
potential new tool for breeders and buyers of thoroughbreds. The
higher the MSB score of a
stallion, the higher the quality of mares to
whom he has produced a foal to race.
My GSV race card databank numbers over 41,000
runners racing in 2008-2009 in North America. I consider the MSB
score to be more reliable if the stallion has 10 or more foals in the
databank. There are 3631 sires in
the MSB databank, but only 1/3
of the sires had that many foals racing. I have generated a MSB excel file and posted it on my
web page. It can be downloaded here.
It is important to remember that the MSB
score is derived only from the dam's half of the
pedigree. For example, Ghostzapper is by Awesome Again out of
Baby Zip. The MSB score
measures only the half of the pedigree
of Baby Zip. The excel file is divided into stallions that have
10 runners in the databank and those that do not. Both halves are
in alphabetical order so that one can use the "FIND" function of excel to quickly
find a stallion. There are also sires in the databank that were
grandfathered into the databank to see if the mares that produced their
best foals had high GSV scores. For example, Man O'War is the
sire of 4 foals in the databank [War Admiral, etc.].
I have added the
average GSV score of each stallion's progeny to
that MSB excel file in
another column. Since the GSV is the average of the stallion's
GSV and the dam's GSV score of a foal, the GSV score represents both
halves
of the pedigree [as opposed to only the bottom half of the pedigree
with the MSB]. I
am including the stallion's average GSV
score in the excel file because the GSV of the sire can be so high that
many breeders not fully fluent with the GSV will misinterpret the GSV
score. For example, if a thoroughbred has a GSV of 70.00 that
sounds great. But what if the sire brought in a GSV of
80.00. This means that the Dam GSV average was only 60
[(80+60)/2]. Not quite so impressive!
If
the sire's average GSV score is a lot higher than its MSB score, then
either the sire has been bred to a poor book of mares or the sire's GSV
score is so high that it would be impossible to have a book of mares
that would be close to the sire's average GSV. For example, A.P.
Indy has a sire average GSV score of 77.50 and his MSB score of
74.24. A.P. Indy brings GSV score of 80.75 to his progeny.
Only a truly good stallion could attract a book of mares with a MSB
score of 74.24 [(80.74 +74.24)/2=77.50].
Conversely,
Yes It's True's average sire GSV at 63.91 is lower than its MSB score
of 64.97. This means that the sire has either been bred to a
higher quality of mare's than he brings into the pedigree himself or
his own GSV score is so low that it is not hard for him to attract a
book of mares with a higher GSV average than his own GSV
score. Yes It's True has done so well at stud, that it is
entirely reasonable that he is attracting mares with higher GSV scores
than himself.

As
the
originator
of
the GRASP scores from which I derive the GSV, I
offer the ONLY up-to-date GSV scores in the world. Each year my
Professional GSV program may be
purchased for $300, which entitles the buyer to free updates during the
year and renew the program the following year for only $150.
There
are currently over 40,000 thoroughbreds in the databank for which GSV
scores will be instantly generated. GSV scores for all other
thoroughbreds worldwide can be generated using through four different
methods by the GSV Professional program. The most difficult aspect of
understanding a thoroughbred pedigree is the value of the genetic
strength of the broodmare's pedigree
