Weekly Data Overview
From July 20 to 26, 2026, Canada 28 held a total of 2,815 draws. The frequency of big and small numbers was nearly even, with big numbers accounting for 50.05% and small numbers 49.95%. In terms of odd/even ratios, odd numbers made up 50.41% while even numbers were at 49.59%, closely aligning with theoretical expectations. This stable distribution suggests no significant deviations in trends, though some interesting fluctuations are worth noting.
Review of Data Trends
At the start of the week, on July 20 and 21, the data leaned towards big numbers, reaching 49.5% and 50.87%, respectively. However, on Wednesday, July 22, the proportion of big numbers peaked at 52.62%, marking the week's high. The dominance of big numbers then gradually diminished, with small numbers slightly rebounding on the 24th and 25th to 50.75% and 50.62%, respectively. By the weekend of the 26th, the ratio returned to a near-even split.
The odd/even ratio also experienced fluctuations. On July 23, the proportion of odd numbers dropped to just 45.27%, significantly deviating from the theoretical 50% and marking the week's lowest point. By the latter half of the week, the odd ratio rebounded to around 50%, indicating notable variability in this metric.
AI Algorithm Performance: Star of the Week
This week, the performance of 30 AI algorithms was analyzed. Among them, the Anti-Martingale algorithm stood out, achieving a leading overall hit rate of 45.29%, a 2% improvement compared to the previous week. Following closely were the Local Entropy and Kelly Criterion algorithms, both tied at 44.87%.
It's worth highlighting that the sample size for this week reached 11,220, lending greater statistical significance to these results. The anti_martingale algorithm's number prediction accuracy was particularly impressive at 53.83%, significantly outperforming other algorithms.
Tracking Extreme Events
Between July 23 and 26, several rare extreme events were observed. For instance, in draw number 3460446, a triple number "4" appeared, and on July 23 and 24, multiple instances of triple numbers were recorded. Notably, July 24 saw repeated occurrences of a sum value of 0, an exceptionally rare event compared to historical data.
Popular Sums and Span Analysis
The most frequent sums this week were 13 (210 times, 7.46%) and 15 (207 times, 7.35%). Regarding span, the span of 5 was the most active, accounting for 15.31%. This distribution aligns with historical data trends and may be a focal point for players seeking strategic insights.
Summary
Overall, this week's Canada 28 data exhibited stability while also showcasing short-term fluctuations. The anti_martingale algorithm's performance deserves attention, and the occurrence of rare extreme events continues to inspire new strategies for players. Data enthusiasts might find valuable insights by delving deeper into these phenomena to uncover potential patterns.
