Take any instance of a given lottery event. After you update the lottery draw in your database, the standard deviation for that draw can be located in the summary table of the WN History Tab.
I think I tried a simple back test by hiding that value. I then generated a full package and filtered using the standard deviation.
ex. Minimum - 11.10, Maximum - 11.11
The actual standard deviation was 11.11. Even if there are 12000 values left in the package after the filter. The winning combination should be there? However, the most that I find using the "remove Match in" on the Visual Package tab is 4/6. I have repeated this several times. I am sure there is something that I must be doing wrong. I have tried shifting the floor and ceiling but I can not filter out the winning comb. This is a sanity check...
