In one of the first posts of RL-Logic (sorry I don't have the LP link, but you can do a search) he introduces the concept of counting real digits from a number of past draws. In short, if you take the numbers from any draw the single numbers 1-9 are prefixed with zero. Theses zeros are not considered real digits. All the rest of the digits are. For example in the draw, 01-07-10-14-31-37, distribution of real digits is:
0-1, 1-3, 2-0, 3-2, 4-1, 5-0, 6-0, 7-1, 8-0, 9-0. In this example the 0 taken from the 10 is considered a real digit.
If you take a distribution of real digits resulting from a number of past draws, you'll find that the real digits 1,2, and 3 occur most often, so the key numbers you'll want to look for are:
1, 2, 3, 10, 11, 12, 13, 20, 21, 22, 23, 30, 31, 32, and 33. Determining just how many of these key numbers you want to be included for a given draw is a dertermination that has to result from your own personal analysis. Note: This only applies to the 5 ball game where the highest number ranges around 39.
Looking at several past draws from different states, I have observed that in five consecutive draws, at least one draw contains two of the numbers: 1, 2, 3, 10, 11, 20, 22, and 33. You can verify this by checking the past draws on your local circuit, or other circuits, or with a program such as Lotwin(even the demo version. You'll be able to enter the filter and view the results).
For the 5-39 game there are 575,757 possible draws. With this filter, the playing field is reduced to 146,160 draws(a little more that a quarter). Combining this filter with others could lead to a manageable number of draws to play over the next five day period.
