How it works
The math behind every bet.
Explained simply.
Used every night.
Algorithm Factors doesn’t ask you to pick more winners. It asks you to identify when the public has underpriced a horse — and bet only then. Here is exactly how that works, step by step.
The core idea
Most bettors lose because they are trying to predict outcomes. Algorithm Factors is built on a different question entirely: not who will win, but whether the price being offered is worth the risk.
That question has a mathematical answer. The Algorithm Factors system produces that answer for every horse in every race — every night, before the gates open.
What makes this different
Every other handicapping tool focuses on finding winners. Speed figures, trainer stats, pace projections — they all try to pick the horse that crosses the line first.
Finding winners is not the same as making money. A horse can win 40% of the time and cost you money on every single bet. Algorithm Factors focuses on price — the one factor every other system ignores.
The mathematics
One equation controls whether you win or lose. We give you control of it.
All gambling — casinos, lotteries, horse races — is controlled by the expected value equation. Casinos use it to guarantee the house always wins. The race track is different because the public sets the odds, not the house. The public makes mistakes. When they do, the expected value equation can work in your favor.
Edward O. Thorp — mathematician and pioneer of modern probability theory — proved this principle by beating blackjack. He discovered that when conditions were right, a skilled player had a mathematical edge. Algorithm Factors does the same thing for horse racing. It identifies when the public has mispriced a horse and the math is in your favor.
Over 13 million data points analyzed. Multiple complex algorithms. One output: the true probability of each horse winning — independent of public money, trainer angles, or handicapping opinion.
The expected value equation
Expected Value =
(Probability of Winning × Amount Won)
− (Probability of Losing × Amount Lost)
What this means in practice: A bet is only worth making when the expected value is positive — when the true probability of winning multiplied by the payout exceeds the probability of losing multiplied by the stake. Algorithm Factors gives you the true probability. The tote board gives you the payout. You compare the two.
The process
Five steps. Every night. Before the first race.
Receive your data files by email
Every evening, typically around 11 p.m., subscribers receive an email with TXT data files for every major track running the following day. You wake up with the math already done.
Load the Race Analyzer
Open the Gary Levin Race Analyzer in your browser. Drag your data files onto the drop zone. Every horse in every race loads instantly — win probabilities, fair odds, and a Verdict for each. The color coding makes overlays visible at a glance — no calculation needed. Use it at home or bring it to the track.
Compare fair odds to the tote board
When the tote board shows a horse at higher odds than the Race Analyzer’s fair odds estimate, the public has likely undervalued that horse. The rule of thumb: only consider a bet when actual post-time odds are meaningfully higher than our fair odds estimate. That’s when a genuine edge exists.
Read the Verdict before acting
Every horse receives a Verdict — Elite, Strong, Fair, or Weak — based on how it rates against 10,000 similarly situated horses. Use the Verdict alongside the fair odds to confirm the edge is real. An Elite horse showing at a significant overlay is your strongest signal. A Weak horse at any price is a pass.
Pass most races — and mean it
The majority of races will not show a genuine edge. Passing is not a failure — it is the strategy. The discipline to wait for the right conditions is the single most critical skill a profitable bettor can develop. The Race Analyzer makes it easy: no edge in the numbers means no bet.

See it in action
This is how a subscriber reads a race.
The simulation below shows how the Race Analyzer works in practice. Each horse has a fair odds estimate from the algorithm. You compare it to the actual track odds on the tote board.
In this example, Iron Patience is showing at 11-1 on the tote but our algorithm estimates 6-1 — the public has significantly undervalued this horse. That’s an overlay worth considering.
Desert Wind at 22-1 against our 14-1 estimate is another potential overlay — and a strong exacta candidate with Iron Patience if the fair odds confirm the payout is worth it.
Morning Thunder, Crown Factor, and Late Move are all passing situations — the tote has priced them at or below our estimates. No edge. No bet.
| Horse | Algo | Track | Edge? |
|---|---|---|---|
| Morning Thunder#3 · Post 1 | 4-1 | 3-1 | Pass |
| Iron Patience#7 · Post 5 | 6-1 | 11-1 | Edge |
| Crown Factor#1 · Post 2 | 2-1 | 8-5 | Pass |
| Desert Wind#9 · Post 7 | 14-1 | 22-1 | Edge |
| Late Move#5 · Post 4 | 12-1 | 9-1 | Pass |
The golden rule
Only bet when the actual odds are meaningfully higher than the fair odds.
This single rule is the foundation of the entire system. When the tote board’s implied odds are significantly higher than our fair odds estimate, the public has made a pricing mistake. That’s when the expected value equation works in your favor.
When the gap isn’t there — and most of the time it isn’t — you close the Race Analyzer and wait. Patience is the edge.
The three scenarios
Track odds significantly above fair odds
The public has significantly undervalued this horse. Expected value is positive. A bet may be justified — check the Verdict and your bankroll rules before acting.
Track odds slightly above fair odds
A small edge may exist but not enough to justify action. Monitor to post time — odds can shift significantly in the final minutes.
Track odds at or below fair odds
The horse is fairly priced or overbet by the public. No edge. No bet. Move to the next race — or go home.
Delivery schedule
Your data arrives before you need it.
The nightly delivery is designed to give you time to load the Race Analyzer and review every race before race day — so you arrive at the track with a plan, not a guess.
All major tracks are covered. As a general rule, only bet tracks with a win pool of at least $20,000. Larger pools mean more accurate public pricing and more meaningful overlay opportunities.
Nightly delivery
TXT data files emailed for all covered tracks the following day. Load them into the Race Analyzer as soon as they arrive.
Review before you go
Open the Race Analyzer, load your files, identify overlays and Verdict ratings. Arrive at the track with a plan.
Compare to the tote
Track odds shift as post time approaches. Compare final odds to fair odds and act only when the edge is there.
