For the last month, I have been trying to find a pattern to narrow down the pick 4 in individual states using 30 sets of numbers of less per play. I am not even focusing on STRAIGHT sets, but more focused on BOX sets as the chances increase a ton. It worked great so far in February and was only using 20 sets per draw, but January was absolutely horrible with major loss.
That is why those of us who create methods/tests suggest over and over to BACKTEST each method for your state before investing money. Also we call it paper testing. Put your numbers on paper as if you are really playing the lotto and track your results.
At first, you kick yourself in the wazoo when your numbers hit and you really didn't make any money... but when you don't hit for a week or two with a test, you are glad you didn't invest the money.
Play smart and you can not so much as "win the lotto", but make a nice profit.
