Numbers (Power 6/55)¶

Frequency per ball (all-time)¶

Every ball with its observed count. The dashed line marks the expected count (draws * main_count / pool_size). Bars far above or below are eye candy, not signal -- the chi-square check on the overview confirms the residuals are within fair-draw bounds.

Hot / cold rankings¶

The top 10 most- and least-drawn balls over all recorded history. "Hot" does not mean "more likely next draw" -- see the caveat.

Overdue table (longest current gaps)¶

The 10 balls with the longest current "draws since last appearance".

Parity distribution (odd-count per draw)¶

How many of the 6 main balls were odd. The expected distribution is roughly binomial (Binomial(6, 28/55)) -- a bell curve centred on 3.

Low / high distribution¶

Low = ball <= 27, high = ball >= 28. Same shape as parity for the same combinatorial reason.

Decade buckets¶

Ten-ball decade bins (1-10, 11-20, ..., 51-55 -- the last bucket is short). Counts are ball-placements, not draws.

Last 50 draws heatmap¶

Rows are balls, columns are draws (most recent on the right). A cell is shaded when that ball appeared in that draw.

Chi-square residuals¶

Per-ball (observed - expected). Most bars should be small; balls that look "lucky" usually have residuals well inside the Wilson-style fair-draw band.
