Hi,Pradeep,
First ,about ball, maybe it means two different things,there are 49 numbers(or digits) for 6/49,but somebody likes to call they balls,I am used to call them numbers. every time 6/49 picks 6 numbers,I divide these numbers into 6 balls according to order from small to large,I do this inorder to set up the graph, then analyze the grpah. Logic is contained in the graph, you may discover the relationship between balls and numbers,this relationship is logic. Of course, you also may discover logic through other way.
I set up many graphs to analyze movement of balls, directions, ranges and positions are three main steps for analysis.
