List the Pick 3 singles by low sums, high sums. Separate each sum row by consecutive pair and non consecutive pair combos. You will now have 4 groups of 30 combos. LS/CP, LS/No CP, HS/CP, HS/No CP.

These 3 pair groups. A 14 17 47, B 25 28 58, C 36 39 69  are in 63 combos. 54 combos do not have them. Total 117. The remaining 3 combos are 147-258-369.

Study root sums. A 147, B 258, C 369 and the pairs. 

Example: Root Sums 3-6-9. The only time the above pairs appear are as combos 147-258-369.

Track the Root Sums as three columns A B C. On the pairs use four columns as A B C and No Pairs. No Pairs are the 54 combos that do not have the above pairs. You will now know what combos to play, when to play them, and when not to. Good  Luck!!!
