Roman,
In my opinion the best advice about betting was what Sean Bartholomew said
in an interview way back - he determines what to back then sets out to get
as much money on at the best price he can; succinct but who can rationally
contradict a successful approach?
RKOZ: Cannot knock that principle at all.
An example of the advantages of early betting - yesterday my best "over" ,
viz price obtained divided by SP/SOP was Nhill 3/7, where I got 6.00/1.80
(limited by MBL to $200/$500) at 9:29am and it SP'd at 2.00, Top Fluc also
2.00, with 2.10 available on-line at the jump.
It paid 1.80/1.80 Top Tote, varying from 1.60/1.04 (Vic) through 1.80/1.60
(NSW) to 1.80/1.80 (Qld - place pool $651 - if I'd bet $500 into the pool it
would have paid 1.00).
RKOZ: Wow, that's the dream result we all want just once a week!
The average price of place bets I make is 6.5, the average win price 30.9.
Don't recall the last time I backed a favourite that was favourite when I
bet.
RKOZ:You certainly forage in the toughest area, Len.
The massive jump in TAB's take-out on exotics a few years back (to pay ZR
etal rebates?) killed my ability to make a good living betting into TAB
pools, so reinvented myself yet again - don't know how many reinventions
I've left in me; maybe the one I'm working on now will be the final hurrah!
RKOZ: I have never made anywhere near a successful exotics approach due to
trying all sorts of approaches I suppose rather than a static X for win y
for 2nd and Z for 3rd in trifectas.

Hi Len,
In between Caul races saw your post flash by.
You WILL note I said "most punters" and not a desperado like yourself!!!
Wow, that's why you win - it's all about the work pre post leading into post
time.
I have been pricing selections since June and have by the end of today a
mere 268 mostly Victorian races but comments for them all and boy I find
that tough enough.

" Re computer generated ratings: what a waste of time for most punters
simply because of time and so many races."
My time:
(1) Daily download of yesterday's (or that day's if available before
bedtime) results, correction of wrong jockeys and update of databases, 5 to
20 minutes per day (5 if no sus jockeys, can be 20 if a number to be chased
up from Stewards Reports, videos...). Not time important, as long as it's
done before first bets (jockey ratings are recalculated daily - there's
"never" a horse backing up from yesterday).
(2) Download of fields for day and initial processing - 4 to 10 minutes
depending on number of fields.
(3) Download of scratchings and jockey changes after official scratchings,
and updating fields - 2 minutes, but can be longer if the download is behind
and I have to manually scratch and enter jockeys.
Repeated (3) as required (eg WA scratchings)
(4) Program to analyse, produce ratings 1 minute.
(5) Download of 10 bookmaker's prices 1-3 minutes depending on number of
fields - 2:10 minutes today.
(6) Program to match ratings to prices and produce recommended bets 1
minute.
(5) and (6) repeated at will to produce recommended bets with new prices.
8. Strategies with large numbers of selections - >10% of available races
tend to 0% POT over time with a plus/minus 15% over any 12 months.
RKOZ: At all odds of selections seems right as the longer the odds the less
chance of winning. and:
best price/cost averaging across TABs is worth 5% and using a bookie maybe
worth another 5%.
For large n, and excluding bets where there has been a late scratching (and
thus likely deductions):
I average 1.24 times Final Top Win ODDS (NOT price) from the 10 bookmakers
(which is a tighter market than SP) and 1.15 times Final Top Place ODDS (and
1.37/1.29 for those that do place) Which should be enough to win, but you
still have to bet on the right horses, but if 1. The market is efficient -
like the stockmarket, there is no strategy that is better than the market
over a large number of selections, and I consistently could get 1.24/1.15
times final odds, in theory I could pick by throwing darts and win.

First of all, greetings and salutations to all. I hope you have all had a
great Christmas time with friends and family and the same for New Years Eve.
As I am awaiting Caulfield I thought I would comment on the posting from
Tony. I will do this with the RKOZ: interjection below
Criteria for a successful selection strategy has evolved to At least 150
selections over 12 months Remove the best result from every 20 winners
Produce 10% POT flat stakes (and this is now eked to 1-2%) And I still don't
understand that.
Fourteen observations on the punt
1. The market is efficient - like the stockmarket, there is no strategy that
is better than the market over a large number of selections (although there
may be people who hedge and arbitrage the betting market - bookies?)
RKOZ: The word "strategy" is incorrect, I feel< and it should state the
market order is efficient, that is, favs win more than 2nd favs who win more
than third favs etc
2. Like the stockmarket, the real players use information that is not
available to the wider market and not reflected in machine generated ratings
RKOZ: Agree to a certain degree. Unknown info is an insiders market but I
think it is more the use of public information and how you use it that makes
the difference. An expert in distance does better, perhaps, than a punter
who studies breeding as the first is based on history whereas the second is
based on supposition yet the same info is available to all. Other areas of
the punt i.e. days since last raced or jockeys are the same.
3. Machine produced ratings perform best with races 1000m-1800m and are
biased to horses that run on the pace.
RKOZ: First part disagree but certainly favour those who race near the lead.
4. 2yo, jumps, firstup, greater 2000M are not harder than other forms of
racing but seem to require specialist skills.
RKOZ: Contradictory. It must be harder if you need specialist skills,
surelyl!! All aspects of the punt require special skills
5. Ratings perform as well in metro, provincial and country racing
RKOZ: All depends on GIGI (garbage in, garbage out) but I don't use ratings
so don't know if there is a difference or not.
6. It is easier to pick horses that will lose than horses that will win
RKOZ: That's no great insight.
7. Plus 50 units is as good as it gets for any reasonable selection strategy
- 150+ selections over a 12 month period - maybe for any selection
strategy.
Perhaps plus 100 units is as good as it gets for anyone anywhere except the
exception.
RKOZ: Just not enough stats there to understand the whole premise but I
guess the suggestion is winning 50 units on 150 outlay. Gee, rack it up for
your next house buy if you can do this.
8. Strategies with large numbers of selections - >10% of available races
tend to 0% POT over time with a plus/minus 15% over any 12 months.
RKOZ: At all odds of selections seems right as the longer the odds the less
chance of winning.
9. Personal selections add at most 5% to any rules based selection strategy
over time
RKOZ: Assume means on top of a computer generated system. Would agree.
10. The easiest strategy appears to be based on identifying a couple of
hundred true favourites a year
RKOZ: Yes, agree. Hard to do but they are there.
11. Most identifiable true favourites are widely identified and are the late
mail and firm into favouritism if they aren't already.
RKOZ: Don't really know.
12. Reasons true favourites don't win -10% over-rated/20% bad day/30%
jockey/40% others under-rated
RKOZ: Seems reasonable.
13. Money management - best price/cost averaging across TABs is worth 5% and
using a bookie maybe worth another 5%.
RKOZ: Don't know about an extra 10% overall but yes plus 5 is certainly
there.
14. There are many many other selection strategies that may or may not
Perform
RKOZ: So what. Dumb comment - means nothing.

RKOZ: Not sure about the rest.
>From my point of view the author isn't really saying anything most solid
punters do not already know. The better punters have researched their areas
of interest (Len with jockeys as an example) and know those over and
underbet and those who are poor back in a field It would be the same with
trainers.
Re computer generated ratings: what a waste of time for most punters simply
because of time and so many races. It would be far easier to tackle the
first four favs with the finest of microscopic investigation. AT least some
of the ratings work has been done by the price assessors and then by race
time others have added their knowledge. From there it is a matter of whether
you agree and if you are good enough you win.
Lunch is ready!!
Ciao
Roman Koz
