Number Hit Interval Analysis
Number hit intervals is a statistical tool for analyzing PowerBall Plus lottery that identifies patterns in the intervals between each number's appearances in draws.
This method is based on counting the number of draws between repeated occurrences of a specific ball. The interval analysis helps identify numbers that are 'due' to appear in upcoming draws.
Based on the last 20 draws for PowerBall Plus lottery: Field # 1: ball 22 has been absent the longest (depth 18 draws), ball 15 appeared most recently (depth 0). Field # 2: ball 3 has been absent the longest (depth 18 draws), ball 1 appeared most recently (depth 0). Full interval table is shown below.

Key Hit Interval Metrics
Arithmetic Mean
Average number of draws between repeated occurrences of a number
Median
The value that divides the interval series in half
Depth
Number of draws since the last appearance of the number
Standard Deviation
Measure of value spread relative to the mean
How to Use Hit Interval Analysis for PowerBall Plus
Analyze number depth
Pay attention to numbers with high depth (long overdue). If depth exceeds the average by 1.5-2 times, the number may be ready to appear.
Compare with the median
The median shows the typical interval. If the current depth is close to or exceeds the median, the number may appear in upcoming draws.
Consider standard deviation
Low standard deviation indicates interval stability. Such numbers are more predictable in their behavior.
Combine different types of numbers
Include both 'ripe' numbers (high depth) and numbers with average indicators in your combinations for a balanced strategy.
