Trying to win on the Belgian pick 3 game has shown me that the most basic solution or filter might be the best of them all, if a way is found to implement it, you got it right DIGITS, filtering digits out of a source of combos or in other words, wheeling digits to make combos.
All other filters are trash when compared to this, Digits or filtering out digits or wheeling them is the most basic and yet the ultimate filters technique, nothing compares to it.
Now I now that maybe for the most part I have been wasting my time for the past few years trying to develop and use other filters.
At the very beginning I started learning with digits and they seemed too simple a technique, I wanted to complicate things as much as possible, so I left the digits alone, I thought that they were worthless, you know the digits frequency technique.
I now think that if a way or ways are found filtering out single digits and then wheeling the rest is or can be the very best filter technique of them all.
Finding this thread just gave me an excuse to post this thought.
