NOTE: Make things easy for yourself. Use the KEY PREDICT feature. IF you think L1 Hit/Miss column will be a HIT then it's PURPLE numbers. IF it will be a MISS, it's GREEN numbers. Just remember, IF it's a HIT, the 1st digit of the winner MUST be in the last 3 winners. IF it's a MISS then the 1st digit of the winner is NOT in the last 3 winners. THIS will help you eliminate numbers that do NOT meet these requirements in the KEY PREDICT feature.
DO NOT restrict yourself to one PAIRSUM. Because you are playing very few numbers with this strategy, you can play multiple pairsums. I suggest you play within GREEN, PINK, BROWN.
Here is a CHART you can use to implement the strategy lets call "PICK3 BINARY COLOR STRATEGY"(Red numbers are the ones that win the most).
What we can also do is create an AUTOMATED page that inserts Pick3 numbers into the boxes before every draw. All you need to do is click a button and you'll see the page. You will only have to choose one or more PAIRSUM+COLOR and play the numbers. Each box will contain less than 5 and 10 numbers. And you will be able to apply the filters to them. For Example, if you think L1 Hit/Miss will be a HIT, you simply choose HIT. It can drastically reduce the numbers in a box to 1-2 numbers without removing the winner.
