Number Groups Manager window opens from menu Tools - Number Groups. In this window you can see a list of all number groups defined for the current lottery. Use the buttons at the top of the window:
It is possible to create number groups consisting of hot, cold and warm numbers. First select past draws to calculate hot/cold numbers from. Then choose how many of those draws should be used to find hot numbers. Next you need to specify the minimum occurrence of hot numbers and the minimum occurrence of warm numbers. The actual distribution of pool numbers into hot/cold and warm categories is given in the table at the bottom of the window.
For example ten latest draws in Expert Lotto 6/49 demo lottery are:
|2010/28 Sun 2nd||23||29||36||42||44||47|||
|2010/28 Sun 1st||06||13||14||19||41||42|||
|2010/28 Wed 2nd||02||13||16||17||25||40|||
|2010/28 Wed 1st||16||18||22||23||28||29|||
|2010/27 Sun 2nd||01||06||12||24||32||41|||
|2010/27 Sun 1st||02||15||22||29||30||37|||
|2010/27 Wed 2nd||20||23||25||30||33||35|||
|2010/27 Wed 1st||08||11||19||26||48||49|||
|2010/26 Sun 2nd||08||11||18||32||36||38|||
|2010/26 Sun 1st||05||06||11||31||40||43|||
Let's use the following settings to create Hot/Cold/Warm groups:
It means the hot/cold numbers will be calculated from the occurrences of pool numbers in the latest 10 draws (see the table above). The draw limit field divides the table into two parts. The latest 4 draws have orange background, the previous six draws have blue background.
A number is hot if it hit at least two times in the orange section (before draw limit) and at least once in the blue section (after draw limit). In this example there are only two such numbers - 23 and 29.
If we change the settings to Min occurrence of hot numbers before draw limit: 2 After draw limit: 0 then there will be five hot numbers - 13, 16, 23, 29, 42. They are numbers that hit at least twice in the orange section.
A number is warm if it isn't hot and if it hit at least two times in the selected ten past draws. There are 16 such numbers, for example 2, 6, 8, 11 etc.
All other numbers are cold - they hit at most once in the latest ten draws. There are 31 cold numbers in this example - 1, 3, 4, 5, 7, 9 etc.
Note: Number groups created this way are static - so when you add fresh winning numbers into your database you have to create new Hot/Cold numbers groups to take the latest numbers into account.
Clicking Import button in Manager's window toolbar opens standard Open file window where you can browse a text file that will be converted into a new set of discrete number groups. The file being imported is expected in the following format:
After successful file import it is possible to remove or edit the original imported file - the numbers groups created by the import action will remain unchaged.
