What is Sportsbook Edge?
The Sportsbook Edge is represented as a percentage and that number is the actual edge the sportsbook has over the sports bettor on the moneyline. This edge is how sportsbooks ensure they can turn a profit over the long run even on moneyline bets.

How is Sportsbook Edge calculated?
The Sportsbook Edge is calculated by adding both teams win probability percentages together and subtracting 100 from that total.

Sportsbook Edge Formula:

(Team 1 Win Prob %) +
(Team 2 Win Prob %) - 100
= Sportsbook Edge Percentage %

What's considered a good Sportsbook Edge percentage?
Well generally, the lower the number the better it is for the sports bettor. Usually the Sportsbook Edge percentage does not go lower than 2%. Generally speaking anything from 2% to 3.5% is considered a very good Sportsbook Edge for the sports bettor, 3.6% to 5% is considered average and is usually what is available. Anything over 5% is considered high and is very hard for the sports bettor to turn a profit over time.

Sportsbook Edge Ratings:

BETWEEN 2% AND 3.5% = GOOD

BETWEEN 3.6% AND 5% = AVERAGE

OVER 5% = BAD

What else should I know about Sportsbook Edge?
The Sportsbook Edge gets lower as it gets closer to the start of an event. So for example, the Sportsbook Edge for an NFL game is higher earlier in the week when the odds are first set and gets lower and lower as the week goes on, and it will be at its lowest right before kick-off.

Lower ranked sports leagues, prop bets, and all live betting in general have very high Sportsbook Edge percentages. Usually well over 5% at all times, this is why sportsbooks offer these types of bets to the public. It's very hard for sports bettors to turn a profit over time betting only on lower ranked sports leagues, props bets, or live betting because of this very high Sportsbook Edge percentage.

How does the AI Simulator work?
The AI Simulator uses large data models and machine learning artificial intelligence to determine a winner and final result for a specific match.

Sportsbooks and oddsmakers use many factors to create the betting lines and odds for every match for the public to wager on, the AI Simulator reverse engineers those same betting lines and odds as well as incorporates other statistical and historical match, sport, and public handicapper consensus data to simulate final match results.

Key AI Simulator Model Data:

• Live Lines and Betting Odds
• Historical Lines and Betting Odds
• Streaks and Betting Trends
• Historical Data and Stats
• Previous Match Matchups
• Public Handicapper Consensus
• Rivalries and Revenge Factor
• Travel and Rest Factors
• Key Injuries or Suspensions
• Weather Factor (if applicable)
• And More Advanced Data!

The AI Simulator also utilizes machine learning artificial intelligence to become more accurate over time. For example with the start of every new season, the AI Simulator establishes a performance baseline and only becomes stronger and more accurate as the season unfolds and more data becomes available. Also keep in mind that simulation results can change each time you run a simulation because of real-time changes in the AI data models or changes of the current available betting lines or odds.

Please keep in mind that the slightest movement in the betting odds, lines, or even a change to the event itself (injury, trade, suspension, location, weather, etc.) can cause the AI Simulation and Best Bets to change completely. Each time you run a simulation, the AI data models use the latest information available at that exact moment in time to generate the final simulation results. For the most accurate and consistent results, run the AI Simulation just before the start of the event.

The AI Simulator will also generate best bets based on the final simulation results. If there is good value or an oddity in the betting lines or odds, the AI Simulator will expose it without any bias or human element, based strictly our constantly updating AI data models.

The confidence percentage included with each simulation is a market-stability score, not a claim of simulation prediction accuracy. It starts at a baseline of 100% and is then systematically reduced or adjusted based on how much uncertainty the betting market is signaling between the opening lines and the current lines. First, the model penalizes large total movement (opening total vs current total), because significant changes in the total indicate disagreement or new information about expected scoring; the larger that move, the more confidence is reduced. Next, it penalizes spread movement, since big changes in the spread imply volatility in the expected margin of victory. The model then applies a further adjustment based on sharp bias magnitude-strong moneyline or spread pressure toward one side reduces confidence because the market is actively correcting itself rather than being settled.

What is Numerology?
Numerology is the study of numbers and their supposed mystical or divine connection to events in life. It's based on the idea that numbers have a deeper meaning than their numerical value.

How Numerology Works?

• Numerologists believe that numbers have a unique vibration that can influence people's lives.
• They use an alphanumeric system to calculate a person's Life Path Number from their date of birth.
• This value is said to reveal a person's unique characteristics, life purpose, and predicted future events.

How is Your Numerology Life Path Number Calculated?
To calculate your life path number in numerology, you can add the digits of your date of birth together until you reach a single digit.

Calculation Formula:

1. Add the day and month of your date of birth together.
2. Add the digits of your date of birth year together.
3. Add the results from steps 1 and 2 together.
4. If the result is a double digit, add the digits together until you get a single digit.
5. If the result is 11 or 22, you don't reduce it to a single digit. These are called Master Numbers and represent a greater potential for success.

How are Numerology Picks Generated?
