[AusRace] An Enigma

G'day Terry - is this what you do? You did say you use a very narrow
subset of data but did not reveal what that is - don't worry this will
shrink to middle memory in a few more days.

 

Another aspect I have been looking at for a while is the API, the
average prizemoney index. To move on, or away from the data that
everybody can use I have been looking at this differently.

If the runners earnings are divided by the number of preparations it
has gone through then a different, more focused, index can be found.
This is ranked also. Its often just re-arranging the top 6 off
API(normalised) but it has assisted in sorting selections for
inclusion in bets. The number of preparations I use is derived from
the first up statistics, then I add one for this preparation.

 

Cheers

 

Tony

Eh,

 

You mean you have not been doing this sort of thing the whole time?

Great thinking outside the box Tony!
Like the Unitab 100 pointers, it does not contain any allowances for
recent form, just peak form.
Some of the 100 pointers, have woeful form and should not be ranked on
top.
One must use more than one criteria or rating to be successful, as you
are doing.
Be interested to see how this pans out for you without going into too
much detail :)

An Enigma

I have been watching this for a few years, checking most days for its
occurrence and it does recur frequently.
If the career figures of a runner are manipulated, de-constructed
almost, then the findings re applied to the selection of runners often
a new set of runners arrive, off the radar from other logical
selection processes.
If a runners career performance figures are modified to place it where
it is in this preparation then these runners can be considered
candidates for selection.
An example Warwick Farm race 6 today.
10 Another Snappy has the career figures 31,7,2,3 so 31 starts, 7
wins, 2 seconds,3 thirds to earn a 38.7% place strike rate. That 38.7%
is the figure everybody uses, it is representative of this runner
endeavours on a race course, over several years.
I had thought that this runner has other information titbits you could
use. Logically it can't call on its first up figures when it is 3 or
more runs in this preparation. You could use the 2nd up figures as
well, to really distill the horses potential with what is left. I
haven't done that to any great degree.
For starters, it is not first up, it's first up statistics are
displayed though so if you deducted those from its overall score would
this provide us with enough right information on which to base a
decision. It may promote it in ranking from 5th where it lingered
earlier.
It's first up record is 5 starts for nothing, zero. So 31,7,2,3
becomes 26,7,2,3 which equates to 46.15% and Another Snappy is
promoted, to 2nd, and is in the mix for inclusion in my betting.

10 Another Snappy won today paying 65.20 and 12.00. Using my rubbery
algorithm I had priced it as $3.40 place.

Summary: obtain the career performance record for each runner, deduct
the first up career performance record, calculate the percentage of
what remains and rank that with the other runners.

This method selected the 2nd place getter also, who was ranked first.
3rd and 4th rank ran 10th and 11th.
I applied a further restriction to runners coming in for
consideration. I used their assessed place % and deducted that from
the new calculated place percentage, the figure obtained after the
first up statistics are deducted. I then rank the resulting figures,
the biggest calculated benefit gets recognition this way. Another
Snappy had a 7.5% boost.
In Doomben race 7, six minutes later, the number one selection, and
the favourite won, $2.40, and got a 25% boost In Sandown race 7,
Kakanui failed to place In Ballina race 7, Neurum won $6.40 In Gawler
race 8, Nishiazabu placed 2nd, rated at $5 to place it paid $8.80,
Mighty Maher placed 2nd, rated at 3.40 it paid 3.50.
In Warwick Farm 7, 2nd ranking Cosmic Engine won paying $2.60. The
flop was Big Cheer.
In Doomben race 8, winner Patronizing was third pick but needed a
place dividend of $5 and was not selected. Top pick was Flaming Mogul
who ran down the track.
In Sandown race 8, top pick Two Hats was not successful.
In Gawler race 9, there were insufficient starters for us, and place
betting requires 8 runners. We picked 2nd and third with this method.
In Belmont race 6 top pick Pinsson, with a 35% boost placed and paid
$5.10 after rating at $2.50.
It may be ok to use both methods, meaning either method, the straight
out top pick after modification or what I use, being the ranking of
the boost the runner receives.
This developed out of a scheme to frank the favouritism of the short
prices that appear regularly now, the perceived best runner in the
field. This has been an ongoing study. It has been worthwhile.
Cheers
Tony
