A 50% subset of the 120 Combinations for Systematic play.
The 120 boxed combinations of non repeating digits e.g.123, are from the 220 group of Boxed sets. The 220 are made up of 120 Straits, 90 Doubles and 10 Triples. Any combination can be made from these boxed sets, 000 to 999. Naturally, there is no reason to play the triples as boxed.
There is a subset of the 120, exactly 60 of them in count or 50%. Knowing about this particular 120 subset will help you make decisions better.

The 120 Combinations groups by leading digit are : 0’s ,1’s,2’s, 3’s, 4’s, 5’s, 6’s and 7’s.
A closer look at the Zero’s group shows that there are 26/36 0r 72.22r% of one kind of set. They are; 012, 013, 016, 017, 023, 024, 025, 026, 027, 028, 029, 034, 035, 036, 037, 038, 039, 046, 047, 056, 057, 067, 068, 069,.
From the One’s there are 6/28 of one kind of set (21.4%) . They are 123, 126, 127, 136, 137, 167.
From the Two’s group there are 15/21 or 71.4% of one kind of set: 234, 235, 236, 237, 238, 239, 246, 247, 256, 257, 267, 268, 269, 278, 279.
In the Three’s group there are 9/15 or 60% of one subset. 346,347, 356, 357, 367, 368, 369, 378, 379.
In the Four’s group there is one from the 50% subset (1/10 or 10% of that group): 467.
In the Five’s group there is one from the 50% subset (1/6 or 16.6%): 567.
In the Sixes group there are 2/3 or 33.33r %: 678, 679.
The Seven’s group has none or 0/1 in the 7's group.
As you can see the 50% subset is not evenly distributed in these groups.
You can see this better by highlighting the sets on paper. If you are trying to select a set from among a particular leading digit group, looking at a short history of a month or two may be enough to make the right decision. If tracked on paper, a notation can be made to the side as to what group a draw came from for easy evaluation of the history.
