Let take X no. of previous draws data and separate individual wining numbers with their position. Final sort individual position with the most happen digit to the least.
eg. Sunday 12 Aug 07 Draw No: 2580
If you count for the 1digit, no.6 is drawn 5 times, and no.1 is not drawn at all. same for 2nd, 3rd, 4th digit.
We have generate number for next draw:
Most Drawn: 6211, 6212, 6219, 6411, 6412, 6419
Least drawn: 1990
This is just an example.!!! Never tested or verified.
I have tried to wednesday and saturday draw results to check if it is close to any winning numbers for Last Sunday draw but this prediction method using 2 previous draws results is not conclusive.
