So, after read this theory here:
viewtopic.php?f=14&t=2500
You can apply it to every single number, every group of 2,3,4,...n numbers.
But you can easily see that from time to time it fails. So, the question is WHY ?
I tried to figured out why and here is the answer:
There are few little error which take place from time to time, like in the following descriptive example:
e.g. You expect the number 45 to be drawn in the next drawings. But instead of 45, it comes to 46 or 44 or even 47 and 43 which means: N+/-1 or N+/-2. And this is the little error.
Another example:
e.g. You expect to be drawn 23 and 38 and instead of this group of two numbers there will be drawn numbers like:
23 and 37
23 and 39
OR
23 and 36
23 and 40
OR
The same variation in first number and the second number is the same as expected.
OR
Variation in both numbers like N+/-1 or N+/-2.
I don't know why this happens but it seems to like some small DNA chain mutation. Maybe during time it forgets the numbers to be drawn and this is the cause of this small variations/errors.
So, maybe someone will be so kindly to create a filter/plugin to do this thing.
Thank you in advance !
