Hi, Stan:
I found the Occurrence of Back-tests in WNH Filter of Statistics is unstable.
For example, when I was making the Statistics for WNH Unique Num Differences and I clicked the button of Back-tests for 4 of Distinct Number Diff Count 0 on 05/16/09 and 05/20/09 separately, their Occurrences are very different between the date of 05/16/09 and 05/20/09 (see the attachment). Especially, the occurrence should be “
Passed†on 05/20/09 since the JP went out when I clicked the button of
OK under the setting of
Remove on the date of 05/16/09. And the same things happen in other dates in the filter.
The same phenomenon exists in the WNH Segments, WNH Hit & Skip Diff in the Statistics too.
Best,
lb

Stan and All:
2) Also, I find the result of the Statistics is very different from the Segments Filter in WNH. For example, after I clicked the Calculate Stats for WNs only, I opened the window of WNH Segments in "Show Stats for,"
then I highlighted the line of 4-1-1 in Column -5, clicked the Filter on the left coner, clicked the buttons of Back-test or Leave/Remove, the both running results of BT & Filter should be same with the results by using the Segments Filter in WNH Page for same column and segment. But they are very different in my EL infact. Why?

filters invoked from statistics are 'dumb' filters meaning they won't back-test correctly if their stats value were calculated from past winning numbers.
fixing this would be a lot of wasted work so you'll have to wait for version 5 to get it working properly
