The most frequently drawn combos in the three game are the 0-1-2-3
By position they will have the highest percentage to appear in either of the three positions. figure which position the 0123 will have the most probable position they will hit in.
Now you will need to figure which of the remaining digits is most probable to hit in either of the three positions.
If I am looking for a combo series to hit higher than the 3 combo my best choice by position of the 456789 will be present.

p-1> 0123 [456789]
p-2> 0123 [456789]
p-3> 0123 [456789]
