Has anyone ever looked at a 3-5 year history file of a pick 3 or pick 4 and then possibly taken the drawings as a reference around the drawing you search for? When you reference your numbers do you ref the first 2, middle 2, and end 2 in the pick 4? I do in fact do this because it is very important when picking numbers. There are some numbers that can be linked to another number, which is sometimes named as their relative numbers, which will also hold some value to your next pick. This is why I know and belive it is really important to have at least a 2-4 year history file available, preferably in excel. Most of the time it seems like the short term 2 digit numbers in the pick 4, forced air drawings.
