In the video below you will see a simplified (and super effective) version of my system. I like it because it is SIMPLE and it WORKS. Here you are only concerned with 9 trinity numbers:
011, 013, 014, 016, 018, 023, 026, 027, 028
With this strategy you will have to look for states where one of these numbers hit and the prediction is this; one of the two lowest digits will hit in the next 1 to 3 drawing. So if 026 hit last, you are expecting a 0 or a 2 to hit in the next one to three drawings. He discusses in the video an important strategy; you only have to concern yourself with the last TWO digits (this is a BOX system) or the back pair.
For example, if 014 hits, you are looking for 0xx or 1xx to hit. Many times you can eliminate low pairs (00, 01, 02) from the back because you are already starting out with a low digit. In the example in the video, he won on the number 158.
STRATEGY; I suspect that the digits in the second and third positions will most likely be in the 3 to 9 range (3-4-5-6-7-8-9) because most of the time a 0, 1, or 2 will be in the FIRST position. This reduces the possible numbers for the second and third positions.
