Well, from what I have learned reading her book, then working the program is if the frequent number drawn in say 20 draws does not follow many of the currently drawn numbers, it's programmed to be "one" of her picks. Then I've noticed the numbers that follow approximately 1/2 of the time are also programmed to come up. I seldom see numbers that were drawn one time on the list, unless they followed several numbers. ERGO: 2,3,4 and 13 drawn 1 time followed the trio. I don't see any true number link going on in any of it.
By number link, I mean if say 13 was followed by 18 4 times in 20 draws, odds would be against it being drawn again. ( If 18 were drawn 7 times in those draws you would see it on Gail's number selection)
So, 13 would have to be drawn with one of the numbers in the line 18 was drawn with to release 18, which would be drawn with a number from the line 13 was in. Or 13 would have to be drawn with 18, which is more common.
Even putting that aside, I still don't really "get" where she is coming from on some of the numbers.
