A late odds and price decline theory

This isn’t the first time I’ve written and talked about it Mapping.

Horseplayers love to romanticize the past, but not everything from that era was nostalgia. Some of it was an edge: earned, honed, and guarded like a secret. ‘Mapping’ was one of those aspects. So were the “Bubbles”. There were others and while the game has always been difficult, and not for the faint of heart, today it is harder than ever for the retail or ‘average’ player.

Long before simulcasting, long before ADWs, long before CAW groups entered the bloodstream of the bag, there were the card guys. We called them charters. And they were real players: calm, disciplined and usually profitable.

The premise behind Charting was to follow the money, which was often revealed by significant odds drops, especially in the exacta and doubles pools.

When the TVs told you the truth

At the time, race tracks had two types of televisions:

  • Most TVs showed it live Myra or track feed.
  • A select few flashed continuous changes in the exotic pools – daily doubles and exactas, before they were mainstream.

And under those TVs stood a dozen regulars, with notebooks and pencils in hand, charting every flash. Every tap. Any anomaly. They didn’t read tea leaves; they were reading the money.

They tracked where exotic pools deviated from the odds of winning. When a 10-1 shot was paired with a 3-1 favorite in an exacta for a surprisingly low payout, the charts took notice. If a horse’s double chances collapsed despite flat winning odds, they noticed it too. These were stories: money moved where only certain people bothered to move it. Even fewer saw it.



It was the hunt for what they believed was the “smart money.” An annoyance to everyone else, but a source of income for them.

If I remember correctly, eight to twelve chart men worked the NYRA circuit every day, and a good handful made enough to call it a living. In that ecosystem, the retail gambler at least had visual access to the exotic flashes — something you simply can’t get today without hitting refresh like a lab mouse in an Ivy League behavioral study. There was also no simultaneous distraction.

Today: a forgotten art

Tracks stopped showing those exotic flashes years ago. You will no longer see rolling exact or duplicate changes on monitors unless you use them AmWager or manually refresh your ADW every 30 seconds, you are blind. Today they show other racetrack feeds.

No lost art.

A forgotten art, an art that no one can practice anymore with the same tools.

And ironically, it disappeared right around the time something else arrived: Simulcasting. Simulcasting has changed a lot in the game. Many good, some not so good.

Have CAWs picked up where the Chart Men left off?

Let me be clear: I’m not claiming anything illegal. I’m not saying CAWs can’t be posted anymore. I’m just saying that it would be naive to think that racing’s most technologically advanced betting groups aren’t at least replicating what the chart-toppers did – except with computing power, real-time pool access and last-second batch betting that makes a pencil and notebook look like a butter knife at a gun show.

This is what we do know:

1. Let’s say that CAW groups realistically deploy 33-40% of the total North American deployment.

That’s not speculation; it is factual, published in industry presentations.

2. They work with direct access to the bins, allowing them to:

  • Track pool movements in milliseconds
  • See how the will payouts change as bets are aggregated
  • Model inefficiencies for dozens of pools simultaneously
  • Strike in the final seconds when no retail gambler can react

That’s essentially mapping, except it’s done mechanically instead of by muscle memory.

3. They specialize in exotic pools where inefficiency is greater.

The same pools that the card men lived in.

So the theory is simple:

Mapping has not died. It was outsourced to algorithms.

The Fix Six: The Blueprint That Still Haunts Racing

It doesn’t take a conspiracy to see how powerful your tote bag visibility can be. Consider the Breeders’ Cup Fix Six scandal. A summary from CliffsNotes:

  • A Pick Six ticket was put together after four races had already been run.
  • It selected the first four winners.
  • Then it ALL went down in the last two stages.
  • And no one noticed until Volponi blew up the Classic 43-1.

That wasn’t mapping; that was criminal manipulation. But what it proved is this:

If someone can see more than the audience, he or she can bet smarter than the audience.

The Fix Six conspirators didn’t need to know the future.

They needed to know the past results and the carrying case structure.

And they almost got away with it.

Volponi was the only horse standing between them and a perfect crime.

Food for thought: could CAWs be the modern solution six – legally speaking?

Once again there is no question of unlawful conduct. But here’s a thought experiment:

  • Suppose a CAW model detects an inefficiency in the late exacta pool.
  • Suppose it also identifies underlays/overlays related to the profit pool.
  • Suppose access to the tote bag allows perfect tracking of every penny that comes in.
  • Suppose $250,000 is fired in the last five seconds.

Is that ‘smart money’? Is that mapping? Is that something the old-fashioned guys with the yellow sanitary towels would have killed for? Or is it something more? It certainly explains the repeated phenomenon that retail players complain about: a horse at 5-1 turning into 5-2 at the half-mile post. Doubles and exactas come in late. Choose five will-pays that melt just before loading. Are those CAWs? Are they inefficient markets? Is it just the modern game?

The truth is probably a little bit of everything.

But it’s definitely worth pointing out that the only group that can follow every blip – every pool move, every late shift – is the same group that holds 30 to 40% of the control. And the retail player? They get whatever their ADW app loads after buffering.

A forgotten skill in an unfair fight

Mapping wasn’t a perfect science, but it showed the public the money. Nowadays, audiences only see the final song – after the CAW gavel has struck. We removed transparency just as the sport introduced players who thrive on invisibility. That’s no coincidence. It’s a case study.

The takeaway

  • Mapping was an art that rewarded observation.
  • Today’s players no longer have the means to practice it as readily available as they used to.
  • CAWs have these tools, and much better ones.
  • Tote-based exploitability has not disappeared; it evolved.
  • The integrity of racing does not depend on nostalgia, but on transparency.

The old card men knew one thing:

Money talks, but only if you can hear it. Today, only a very select few can do that. And that at least deserves a conversation. When you combine CAW’s methodology, the normal sharks and spikes in the water, the voluminous amount of information out there if you’re willing to look and sometimes pay for it, the game’s odds start to make a lot more sense. That doesn’t mean we like it or that it helps, but you can understand it. Follow the money.
