Powerball DOES publish their pre- and post-game tests.
Here's the problem: when the next drawing takes place, they switch ball sets and ball machines, I have seen a number hit 4 times in the previous drawings' pre- and post-test games, but for the next drawing, that number does not show up at all.
And as far as a number such as '8 being overdue', what defines 'overdue' ?
I see 'overdue' numbers all over the place, but the problem is, let's say you have six 'overdue' numbers to choose from, once in a blue moon you will guess which ONE of those six numbers will hit, but that's just ONE number - AND you have to pick the right one. Once in a Pink moon TWO 'overdue' numbers will hit, did you get the right ones ?
And you still have to get the other numbers AND the Powerball.
If, say, a number, we will call it '38', is overdue, how long will you play it ?
Until it hits ?
When do you start playing it ?
If so, it was 58 games old when it hit a week ago, if you started playing it when it was overdue, for the sake of argument let's say anything over 20 games 'old' is overdue, yeah, sure, sooner or later it will hit, but you played it for 19 weeks. There are other things to consider with a number besides it just being 'overdue', but you need to track this for two years before you will see what I'm talking about.
I did not get 38 when it hit, but I did get 17 (28 games old) in the last drawing based on things I have seen in the past. I have seen numbers go 71 games before being hit, and several into the 50's.
