System Ball option 

This option allow you to study small size of winning result. By default, the system is set to use all the main numbers from the winning result. You can choose to use a lesser number of main numbers to use for analysis, thus lesser permutation. This option only applicable if the result is sorted ascending from left to right. The reason been the option will start the main winning number from left to right. If you select system 3 balls, then it will only use the first 3 winning results from left to right as shown below. Please take note that when you use any system that is lesser than the full system, the statistic on the expected hit for Big/Small, High/Low and Grouping would not be correct because of uncertainty involved.
