With this I am tracking my digits in the 2ev 1od/ all even_______1ev 2 od/ all odd
in separate columns.
You will need to study it very carefully to see where the current or previous draws came in the line from previous draw.
You can also spot where the current draw came from in the previous draws.
I may be able to color code some to show you.
Get the hang of how the digits run in a column. Which column the digit is running in and when it may fall in the opposite column. Premium members can use search drawings to find how a digit is running.

Take your draw history and enter it on a line like you see it here.
I enter the number as drawn. after the draw is entered on the line
delete out the digits drawn in the line. Keep your line separated
into three parts, first three digits, middle four digits,
last three digits which I call the out three
