Each historical round is tested using only the draws that happened before it, then compared with a pure random set.
Historical score, not prediction. If draws are fair, every valid combination keeps the same official probability. Past frequency does not guarantee the next result.
Mean count of matching main numbers in each generated set.
How often the generated bonus matched the historical target.
A small historical advantage in one run may be sampling noise. This page is evidence for checking the model, not proof of predictive power.
