...Here in Canada, I believe that only machines and ball sets are used for every National and Ontario Provincial game as of the last time I inquired with The Ontario Lottery and Gaming Commission in Toronto, Ontario, Canada. However, to ensure a more tremendous degree of randomness, or the appearance thereof, several machines and several ball sets are used for several different games. Some sort of coin toss/eeny-meeny-mineey-moe, or choosing ritual is played by the Lottery Commission personnel before the actual draw in order to decide which machines and ball sets are to be used for whichever game to be drawn next.
...Even still, moses, I am very intrigued by the performances of your databases against all lottery games! You've got something worth studying!
...Having realized that fact, are you interested in generating a chart or database with as many lines as needed to illustrate your observations, but utilizing lines of only 9 numbers in each line, ...however, in a lottery game that uses 69 balls?
...If you can't generate for a 69-number game, what's the largest game that your software can accurately handle? What is the least amount of numbers per line that you can chart with a decent degree of accuracy?
...I chose 9 numbers per line for study purposes, just to see how many lines are necessary in your scenario for a 4-hit or more to be present in at least one of the lines during any 5, 6, or 7-number draw, if only 9 numbers are in each line, ...similar to your 7-number/line, 92-line, 49-number database...except it be a 9-number, X-lines, 69-number database?
...What software or tools are you using to track how many hits per line are present in your database charts after a draw? My eyes went buggy trying to do it manually with a yellow highlighting marker after printing out your charts!
