My questions is If my operations above are wrong ? If not, why the preview data always is two : 4582116 or 8769222 except 0. I want to estimate the next result by comparing the change of Preview Data in two or three continue drawings (for example, by comparing 06/06/09 and 06/10/09 to estimate 06/13/09) I can do that for other settings but not 0-0 setting since the Preview data is too crazy to believe. I’m afraid that there is some wrong or bug in the code of setting 0-0.
If you are looking for information for 6/10/09 skip that draw and look at 6/609. Go to WN History, History Differences, look at rows 24, 25, and 26 in each column and see if there are any numbers in those rows.
There are 59 numbers and 40,475,358 combinations in your lotto game, if you remove 1 number you remove 4,582,116 combinations, if you remove 2 numbers you remove 8,769,222 combinations. So, when you BT with the setting you have above and there is 1 number in row 26 the results will show 4582116 failed. When there are 2 numbers in row 26 the results will show 8769222 failed. When there are no numbers in row 26 the results will show 0 failed.
The Remove/Leave button has no effect the item of back-test since the % of BT shows passed % only. In other words, the % of BT tells us the Leaving status of Wns in a special Col. But the Preview data is effected by Remove/Leave button even though the data is not change when you clicking the R/L again.
The Remove/Leave has no effect on search criteria (The setting of HD: 0-6/24-24/0-0/0-6) be it back-test or Preview. Remove/leave is for filtering, remove = remove passing combinations, leave = keep passing combinations. Remove/Leave only works when you click Ok or Apply and you are choosing to either remove passing combinations or leave passing combinations.
I do suggest that you can make some BTs by using 0-0 setting and full package for your Ohio 6/49 focus on the Preview Data if you have free time. Maybe, you can meet same problem (two preview data only) with me.
There is no problem with the data results, it's just getting an understanding of how the filter works. Back-testing results that are in the 90% range is showing you that most drawings no numbers are coming from rows 24, 25, or 26.
