The number we had last night in Carolina Pick 3 was 911 taking Lucky's 1 up and 1 down system (membership required) if you research has produced two triggers for last nights number. Another trigger would be my side by side method that I teach beginners 

simply as 

900 <<<911 922

all your doing with the method above is not changing it from a double but produce the next highest and lower number side by side . never changing the number is important .

Echoing the words of my great mentor (gosh I miss that man) you got back in Sept 091 straight two or three draws later .......never change the way the number falls in Lucky's system.
