Gary,
I think that looking at the total of base digits in the game can tell the story abt. what we can expect. For example looking at 1170 games in 5/42 game
I can see that :
1 base digit occurred - once only
2 base digits occurred- 23 times
3 base digits occurred- 84 times
4 base digits occurred- 235 times
5 base digits occured- 359 times
6 base digits occurred- 287 times
7 base digits occurred- 150 times
8 base digits occurred- 29 times
9 base digits occurred- 2 times
Of course, the fact that 5 base digits occurred 359 times i.e. 30% of the time does not mean that their distribution was : 2-2-1 as it could have been for example
2-3-0. However they show up together 65% of the time in my game, which is negatively biased by digit 4 in the matrix. In 5/39 matrix they should come up, the
three of them together, ar. 70% of the time which only confirms what RL calls them as freebies.
I think that 2 biggest challanges are:
1. to be able to predict how many times they will hit, each of them base ones and
2. correctly guess none-base digits.
As to the second point, perhaps an analysis of occurrence of pairs of non- base digits might help determine which ones are most likely to hit together?
