The Optimizer for Pro Basketball

Query Situations

Query Situations finds historical games matching conditions such as team, opponent, game type, home or road, previous results, rest, point spread, over/under, streaks, winning percentage, and season. Leave a field at All when you do not want it to restrict the search.

1. Select the values and ranges that define the situation you want to study.
2. Select the seasons to include. NBA seasons use their ending year, so 2026 means the 2025-26 season.
3. Click Run Query. The summary and matching games appear below the controls.
4. Review the individual games, not only the aggregate percentages and Z-scores.
5. Click Clear Query before setting up a different situation.

Night Shift and Archives

Night Shift continuously searches the historical database for qualifying ATS and O/U situations. By default, a qualifying situation contains at least 10 games and has an absolute Z-score of at least 1.75. You may change the season range, minimum games, and minimum absolute Z-score before starting.

1. Choose a Research Focus: a specific NBA team, Home Team, or Visiting Team.
2. Choose the first and last seasons and, if desired, filter results to ATS or O/U.
3. Click Start Night Shift. You may use the rest of the program while it runs in the same browser tab.
4. Click Stop Night Shift when you want the search to stop.
5. Use New Archive, Save Archive, or Save a Copy As to organize discoveries.
6. Select a saved archive from Open Archive. Export creates a JSON sharing file; Import opens an archive file received from another user. Clear Archive removes all situations from the open archive.

Each saved discovery includes its recommendation, record, Z-score, sample size, and defining conditions. Use Load into Query to inspect every historical game behind it. Use Delete to remove an unwanted situation.

Daily Predictions

Daily Predictions compares the games on a selected date with the discoveries in the current Night Shift archive. A prediction appears when an archived situation matches the available context for a scheduled game.

1. Open the Night Shift archive you want to use.
2. Open Daily Predictions and select a game date.
3. Click Load Games to display the schedule, available point spreads, and totals.
4. Click Generate Predictions to apply the current archive.
5. Review the matches below the game list. They are ranked by Z-score and displayed with one, two, or three stars.
6. Click Load into Query on any prediction to verify the historical situation and examine its matching games.

Understanding Z-Scores

A percentage alone is not a reliable ranking. A 1-0 record is 100%, while a 9-1 record is 90%, but the larger sample provides more evidence. A Z-score accounts for both the observed success rate and the sample size.

The Optimizer compares an observed ATS or O/U decision rate with a 50% reference. Conceptually, it subtracts 50% from the observed percentage and divides by the standard error. Positive and negative Z-scores indicate the direction of the result; larger absolute values indicate a stronger departure from 50%.

A Z-score above 2 or below -2 is often treated as statistically noteworthy in a single test. Night Shift uses a default threshold of |Z| at least 1.75 so promising situations can be examined further. Because Night Shift performs many searches, some impressive results will occur by chance. Z-scores identify patterns worth investigating; they do not guarantee future results.

Technical Terms

Point Spread and ATS

The point spread is a handicap intended to balance the two sides of a wager. If Boston is a 3-point favorite, it is shown as Boston -3. Boston must win by more than 3 points to cover; a 3-point win is a push. ATS means against the spread and describes the result after the spread is applied.

Over/Under

The over/under, also called the total, is a posted number for the combined score of both teams. The game is Over when the combined score is higher, Under when it is lower, and a push when it equals the posted total.

Situations

A situation is a set of historical games sharing specified conditions. For example, a team, previous-game result, and season range can define a situation. Its historical ATS and O/U records may justify further study when a future game satisfies the same conditions.
