The way I prefer arriving at a set of numbers to wheel is to track my sum range chart and see where the winning number sums are congregating.
Then, the second part is in deciding which numbers I need for use in the wheel. There are all kinds of tricky formulas around to try, but formulas are always in constant change. How can you successfully manage that constant change?
The way I manage the change is to maintain an accurate up to date statistical flow chart. This chart indicates what numbers are hitting, what their status is at the time of the draw, and where they are located within a structured enviornment.
Once I created the proper charts, I began seeing that certain groups of numbers behaved in a peculiarly significant pattern. Two groups of numbers were created by dividing the statistical flow chart into an Upper Tier Group, and a Lower Tier Group of numbers.
Many times 4 or 5 numbers would appear in one particular group of numbers, and the very next drawing 4 or 5 numbers would appear in the other/opposite group of numbers. This peculiar pattern has been observed to occur for up to four or five continuous drawings in a row. There is one problem here. At certain times 4 or 5 numbers, (not necessarily the exact same numbers), appear again from within the same group of numbers as the previous drawing.
Now, this observation clicks a switch, doesn't it? If there is a particular pattern that commenly occurs involving a majority of numbers appearing in a certain group of numbers, and the observation has proved to re-occur repeatedly time after time where 4 or 5 numbers is going to re- appear the very next drawing in one group of numbers or the other, what would you do?
Exactly! You would wheel all of the numbers from each group of numbers and play them, wouldn't you?
Ooooooooh, wait! Ooooooooh, that's waaaaaaaay too many number strings to wager!!!
How can I possibly reduce all those strings down to an affordable amount to wager?
Question answered!!! This is what can be done to cover all the numbers from both groups, (Upper Tier, and Lower Tier).
Observe the Average Sum Chart! View where the last two or three total sums appeared at. If there is a Sum Cluster, or a Sum Cluster Alert nearby, these target sum range's may be considered.
Using 4if5 of 19, and 4if5 of 20 wheels to cover all the numbers, (in example, the OH Rolling Cash 5 of 39), and filtering the totals from each wheel using "average sum reductions."
For instance, using a 4if5 of 19 wheel, reduce the total 345 tic's by utilizing Sum Filtering. Reduce the range of 55 to 154 down to, say, 95 to 105. The median range for a 5/39 Lotto is 100. The reduction can be whatever appeals to you. I like viewing the Average Sum Graph and developing a "gut" feeling for what may happen next, for instance, utilizing the sum ranges outlined in the Sum Cluster, or Sum Cluster Alert boxes.
Once this technique is developed, you will be surprised at what is possible. This application can be practiced until a comfort level is achieved and you can become accomplished!
This is the way I do it...
