when I created  the grid I did not pay attention to how many times each ball 0 thu 9 was used.
But I made a count the other day and the count is fairly equal.

0] 10 t
1] 11 t
2] 09 t
3] 12 t
4] 08 t
5] 11 t
6] 08 t
7] 10 t
8] 11 t
9] 10 t

So what does that mean.
I do not know. Got to figure it out.
