Wes.
Thats (aus and usa) combined for (sydney country) only top=3 only.
As i bet only on selections that open<$6.0 or less on course bookies price
i have only recorded those selections sometimes all three will be recorded,
sometimes two sometimes 1.
Betting on my selections that open longer than that results in a
negative SRF statistical relative frequency of 0.93.
Hence as they are in a negative to save time each night didn't
bother to record them looking quickly all selections would be in the
top 4-5 opening fav's but as many drift can't tell the actual market%.
I would imagine as a guess i would probably cover around 70-75%,
of the market with the prices of those selections that are bet on.
I certainly would reccomend if you can having a look at all your
selections to see the country of the sire be warned different states
will deliver different results as will country metro provincial tracks.
If you are a paid member of dynamic race-odds they have an insert
sires column enabling you to go back in time to check previous data.
