The cumulative wait method

The method is easy to use and requires only a few minutes after each draw to fill in the table. No draws should be skipped, and each draw must be processed. Careful maintenance of the table over a long period of time is the key to the success of this method.

In this method, all numbers are divided into three groups "working," "waiting," and "resting. Over time, there is rotation, and each number consistently changes its role. When we first start making the table, we don't yet know the roles of the numbers and can allocate them however we want, for example, consider all the numbers as "waiting". When a number falls out, it goes into the "working" group. If it will fall out in subsequent draws, it will remain in that group. If a number fails several draws in a row, we consider it "tired", and it goes into the "resting" group. We will call the "allowed break" the largest number of draws that a number may miss, so that we do not consider it "tired".

Once in the "resting" group, the number is on "vacation". We do not expect it to fall out during the "vacation time", at the end of this time the number goes to the "waiting" group. A number may drop out without having taken the vacation time. In this case, the number immediately enters the "working" group, bypassing the waiting phase.

If you keep the table carefully, after some time, the numbers will be distributed among the groups. Periodically, they will move from group to group, but on average the number of numbers in each group will be approximately constant. It is easy to guess that we will use numbers from the "working" and "waiting" groups for selection. If there are too many of them, we do as usual in such cases: consider the numbers preselected, but for the final choice wait for confirmation from other methods.

What should the "allowed break" and "vacation time" be equal to? These parameters depend on the type of lottery, and you can choose their optimal values for your particular case. In lottery 6 of 49, the break of 3 and the vacation time of 14 are good results.

There is a modification of this method in which the number is sent "to rest" not only because of the break, but also after a certain number of hits (usually three). As a rule, this still slightly increases the effectiveness of the method.
