Had a few questions regarding the predatory habits of the Orca.

First an extreme hypothetical case:

It is the UNCLE BILL BACKYARD DERBY  (often called THE SIESTA STAKES)

Purse:  Dinner and Drinks at PRIME at Saratoga National

It is a Match Race THE WEATHERMAN versus MATHCAPPER

The \'Weatherman\' sheet has him surpassing a 40 year old top of after moving to the barn of TOPCAT.

Mathcapper, who is managed by a rezlegal syndicate, has all of his races well spaced and he has never gone backwards.

Based upon the ORCAputer, Mathcapper should be 1 to 5 and Weatherman at 5-1 or thereabouts.

However, the Backyard Boys include Bud Fox and he has \'inside\' info that Mathcapper took the last train from Clarksville, had some bad chicken at Hatties, warmed up badly and begged Uncle Bill to be scratched.

Meanwhile, some Backyard chemists have juiced up the Weatherman\'s morning java and, based on Shanahan\'s proprietary algorithm, are certain he will run a another new top .

The Backyard Boys move into action.

Total Pool: $125,000
Takeout 20% (Prime ain\'t cheap and this covers drinks, dinner and an Uber driver)

Only 2 beting entities: the Backyard Boys and the Pequodians

The  Backyard Boys bet early placing their 65k on the nose of the Weatherman.
 
Moby Dick\'s Orcaputer naturally spots the huge disparity in odds and plucks his $62,500 (or more in theory) on Mathcapper.

Mathcapper spits the bit and the Weatherman romps home.
The Backyard Boys give Mathcapper a pepto bismol and toast the Weatherman
Moby Dick gets beached

Granted, the example is extreme.
The questions raised are:

At which tracks and which meets do whales operate?
What \'pools\' do they typically bet into?
Who creates the software and the algorithm they deploy?
Are performance figures (such at TG\'s) incorporated into their algorithm?
How does an algorithm handle claims, trainer changes via private transactions, equipment changes, medication changes, feed chages (or how does the computer find out about the Weatherman?)  jockey changes, surface changes, distance changes, etc. etc, etc. (How does the computer avoid Mathcapper?)

I find it difficult to imagine that such highly subjective intangibles could be incorporated into a program since, by their very nature, they are subjective.

My feeling has always been that:
I see the odds pool (exactas, DD\'s WPS etc.) before I bet
I can see the Will pays going one race forward (pik 3 etc.)
I have a pretty good notion of what the return will be based upon my wager.

If there is perceived value you bet.
If there is no value you pass.

To me, having the option to be \"Selective\" is one of the great advantages in wagering on racing rather than other casino games (ex-poker) .

I suppose that the Orca may eating some of my profits but i wager based upon my perceived value proposition.

I will send a private message with more details/opinions later this weekend to avoid the crime of Board Assertion, a class A infraction punishable by up to 3 richiebee reprimands and 2 Rick B brevity warnings (all in good fun guys).

As for a few facts from this meet, Chris Richard has been my favorite trainer followed by Karl Broberg and I caught on very fast this year after Jack won two races right away.  Both have been \"autotoss\" in the horizontals all meet. These are only Oaklawn Park stats listed below.

Jack Van Berg:
2016:  55-9-7-11
2015:  53-1-5-7

William Fires:
2016:  30-8-3-2
2015:  42-1-4-2

Gary Hartlage:
2016:  18-4-5-1
2015:  49-3-6-5

Chris Richard:
2016:  37-1-6-8
2015:  97-15-11-11

Karl Broberg:
2016:  29-1-4-2
2015:  62-7-9-8

Robertino Diodoro has been my favorite trainer all meet for seeking out winners scoring every weekend and somehow I\'ve been on him nearly every single time.  He has two in today including heavy, heavy fav Subtle Indian.  Asmussen is heating up the last two weekends and is poised to have a big day with the over/under at 2.5 wins today.  Midwest Thoroughbreds and Roger B. absent from the meeting thus far.

Overall, the meet has been very competitive with few heavy chalks and the ones that are heavy chalks have went down a few times also.  In addition, there aren\'t horses \"running off the screen\" or \"rebreaking like a tremendous machine.\"  I usually don\'t enjoy the Oaklawn meet.  But I will miss this one as miracle jobs have been few and far between to my eyes (yikes?...I might be in assertion territory).  I do not study it to the minute detail Boscar does but the payoffs seem to be generous in the win, exacta, and trifecta pools as compared to other tracks for the last few years.

Last one:

Bob Baffert:
2016:  3-0-1-0 (Off the board in 2 3yo stakes)
2015:  4-3-1-0
2014:  5-1-1-1

EDIT:  TGJB has stated that the better info is the number power trainers have shown last year vs. this year vs. pre-Oaklawn as a better barometer (as compared to win %) of how these guys are doing and I don\'t dispute that and would venture you would see some guys just aren\'t getting the numbers down there this year.

I think the issue is which ADWs a track sells its signal to and allows into its pools.  My understanding is that there are ADWs that are specifically designed to accommodate whales/batch bettors in terms of technology and rebates.  The tracks know which ADWs they are.

One can determine how well the whales are doing by analyzing data regarding the settlements between those ADWs and the track.  It is not information that the public has access to, but the track does.

I couldn\'t agree more Richie.  When these folks get a very large bet down at the last second, and I mean the last second, it can have a severe negative impact on the game.  I can\'t stand watching my horse leave the gate at 3-1 and then as they come around the final turn I look up and now he\'s 9/5.  Anyone on that horse feels cheated, and that drives people away from the game - ironically especially if their horse wins.  Not to mention past posting because there was a \"hiccup\" in the data stream.  

There\'s a part of me that says good for them for exploiting an edge.  Fundamentally I\'m kind of all for that sort of thing.  But at what point does an edge become cheating?  

Certainly past posting should be cheating.

Bit,

If Finley really wants to tackle this, he should ask Chris Kay or Marty Panza to:

1.Disclose the net settlements with all the hubs and explain what that means(we know)

2.Fully explain NYRA\'s position on CAW/whale rebates

3.Confirm that the NYSGC is fully aware of what and who NYRA is allowing into its pools and under what terms.

4.Confirm in detail how the \"other\" gamblers in the NYRA pools are not disadvantaged by the preferential treatment afforded to a few.

As much as I enjoyed reading the analysis of this week\'s ROTW I like Richie\'s choice. While investigating the entries I logged my thoughts fwiw.

#1 Pangburn
Which sounds a bit like a spicy hot Thai dish was convincing winner in last without a stellar ride. Winning in bad weather @LRL and prompt return causes me to think the horse is in good form. However the horse has never put two good back-to-back efforts together.

2. Mei Ling
As RitchieBee points out this gal could be loose on the lead and with the weight advantage may last. After watching her previous races it is apparent to me this one will be on the pace if not the lead. But she\'s been there before and could not out finish the winners (in stakes company). M/L 8/1 is attractive considering she probably won\'t lose any ground today.

#3 House Rules
Well rested, looks to be training strong, capable but doesn\'t get any weight or an Ortiz? This race looks more and more contentious as one goes through the entries.

#4 Include Betty
This mare can\'t be easy to ride. She routinely loses ground on the first turn with no other horses around and a bunch on the second turn while doing her Zemyatta thing. As handsome as Aaron is I don\'t think he\'s up to the task here. Hard to imagine a Tri without #4 in there somewhere. Would be a good payoff however.

#5 Saythreehailmary\'s
This one was unlucky to lose her last. But her running style makes her vulnerable to traffic problems so we can expect some more today. But she is hard hitting and M/L 15/1 seems generous considering this one\'s success on AQI.

#6 Cali Star
The omnipresent favorite albeit this one at 8/5 m/l and surely easier to beat than the 1/9 ROTW candidate. Wolfson\'s success visiting the big apple is credible and an Ortiz is up, my concern is this one loses ground or may get blocked making her favorite rail move? Not infatuated.

#7 Storied Lady
This one had a formless summer in 2015 but looks to be healthy again. Along with her Spotlight cohort from the Biogio Rose 15/1 seems generous and I prefer this one.

Conclusion
Proving once again that RichieBee can oft have good judgement this race is a worthy puzzle and a nice test for Mar In NYNY. The absence of RR, Preciado, Josephson, etc allows me to jump in. Considering I can get a better price on include Betty to show than Songbird to win bet a buck.

Mike,

I started this conversation along with the take out concerns of everyday players with Klueless Kay last year at the Spa. The first week or so of the meet he was very visible and accessible as the gates opened up. I also invited him up to our seminar citing many serious players would like to address some of these issues. Of course he said he would stop by during the meet and never did.

He mumbled some gibberish about the boards hands being tied by racing and wagering  on take out issues and that they were trying to obtain some relief. When I mentioned batch betting and changing odds he looked at me like I had 11 heads!

This political board full of cast offs that couldn\'t get a job anyplace else in the working world will never do a thing that could even possibly effect the bottom line negatively. I\'d love to see the look on their faces when someone mentions banning 20% or more of the mutual pools. Can you imagine the cost of a picnic table if that ever happened?

Top NYRA management not gambler friendly and consistently decline any reasonable gambler request,know that for a fact.Kay a bonafide racing neophyte, his bean counter team cant spell exacta, just know debit/credit/price increase.There is also a faction amongst NY horsemen who perceive the gambler as a necessary evil, fking morons.

One or two NYRA Board members are ok and trying to improve some things but the bureaucratic process thru Albany near impossible.Politicians firmly in charge of many aspects of NY racing.

I\'ve never seen a single race where I thought it had been past posted.

 Have to limit that to after the race is run, someone betting 15 seconds late would be impossible to detect from my vantage point.

Moby should\'ve factored into his algorithm the evidence from my past performances, which showed that when I veer into that netherworld of nasty Hatties chicken and away from my standard diet of hard boiled eggs, I bounce badly next time out.
(loved the Bud Fox reference btw Bob - I can still recite just about every line of Gekko\'s, including the classic Teldar Paper speech).

> The questions raised are:

Pretty much everywhere these days. They started in Hong Kong, which was fertile ground because of the huge pools and the self-contained horse population, but they\'ve long since expanded into the N.American market. The limiting factor for them is track handle - smaller tracks may not be worth their time.

> What \'pools\' do they typically bet into?

All pools. Basically any bet they\'ve computed to have a positive expectation. The natural tendency is toward the superexotics (both vertically and horizontally) because edges are multiplicative. I posted a little bit about this not too long ago: Computer-Robotic Wagering

> Who creates the software and the algorithm they deploy?

There are many imitators now, but the original, and most widely known, was created by Bill Benter and Alan Woods. It took them 5 years and over a million lines of code.

I can only speak for the Benter/Woods model, but not performance figures that I\'m aware of, although I do believe they incorporate some sort of variant-adjusted final time. Benter\'s model uses something like 80 factors, which include \'native ability\' variables like normalized finishing position, race competitive level (ie. purse), final time , etc., along with \'preference\' variables like distance, surface, track, condition (wet/dry, hard/soft), etc. and \'incidental\' variables like weight, post position, trainer, jockey (normalized finish position or win%), etc. All variables are in the form of exponentially recency-weighted averages.

This was the biggest issue Benter/Woods ran into, and it caused them to go through their initial bankroll at least once before they were able to correct the problem.

When the first developed their program, they found that there was a very big bias in their estimates. The horses they deemed as overlays were not winning at the rate they predicted, they were underperforming badly.

What they discovered was that they needed to incorporate the public\'s probability estimate into their model (to account for the so-called \'smart money\'). When they combined the probability estimate from their fundamental model with the public\'s probability estimate (50% weighting to each input), they found that they now produced a set of probability estimates that showed very good correspondence to the actual frequency of winning. And the rest, as Benter says, was history.

They do have to quantify some of the more subjective \'preference\' and \'incidental\' variables. As they do with their other variables, I believe they use a normalized scale on the order of -0.5 to +0.5 or something like that.

Exactly. That is one of the reasons I always compute the odds based on the Will Pays, and then measure my expected value based on those odds, which are generally pretty close to the final odds. I\'m rarely surprised by a horse going from 3-1 in the gate to 9/5 down the backstretch. In fact, if the odds based on the Will Pay for such a horse was 9/5 and his odds didn\'t drop, then I would be surprised, and likely in trouble if I bet him, as the lack of support in the win pool vis-a-vis the Will Pays is usually a bad sign.

Yep. Benter himself estimated that the computer guys have the combined effect of raising the blended takeout by around 2 percentage points. So if a track\'s blended take is, say, 20%, the average handicapper would feel like he\'s playing against a 22% takeout instead.

Since it\'s a zero sum game, the fact that the computer guys are extracting this money from the pools makes it a little harder for everyone else, but as I mentioned in a recent post: Odds Lines: Omniscient vs. Zero Knowledge, as long as you can create an odds line that is better than the public\'s (which is the same thing the computer guys are doing), and your overlays are performing like they should, there is still value to be had.

Best,

Rocky

No problem with any of the conclusions here, except I find that \"2%\" impact  figure a bit disingenuous.

 If that\'s all it was , then no one would notice or care.

 What matters is what happens to the odds on WINNING combinations.

 Exactas going from 100 to 80 is not 2%.   3-1 to 2-1 is not 2%.

 I don\'t believe that figure for a minute.

 Sure, when they get it wrong, the payoffs are elevated, but they don\'t get it wrong all that often , and the \'boost\' in odds is not of the same order of magnitude as the \'cut\' when they get it right.


PS I\'ve watched some Hong Kong pools now that we have access. The odds changes in the Q\'s (no exactas there) can be enormous on the last flash or two. Even with the massive pools, the movements can be even larger than we see here.

belmont3

Thanks for the great explanation.
I guess I have going to have to do some more extensive reading on the subject as my intellectual curiosity has been aroused.

On a different note, The Weatherman said that, despite finishing up the track, you are invited to his retirement party.

It has been \"Heard on the Street\" that the Weatherman will soon unveil  a new financial product that is currently being tweaked during beta testing.
 
It is called \"Sunny Skies\" or a \"Meterorologists Guide to a Rebated Retirement\"
First seminar being held at the Saratoga Harness OTB.

Well we notice, mostly, when it hurts us.  Sure, its evident and pisses us off when our exacta is $20 lower.  We don\'t notice the five previous times when the exacta is four dollars higher

If you think you\'ll be right 5 times against the pros for every time you\'re wrong, you\'re wrong.
