My current method is still using my 10-digit number and my spreadsheet that I designed, but I'm using only the opposite distribution as the last draw and the opposite High/Low.
For the Texas 01/05 Midday here is what I'm talking about:
Here is the 10-digit number:
If we call the first 5 digits (to the left of the "-") A, and the right side B, I will play A1-B2 (like 629, 624, etc.) or A2-B1 (like 682, 689, etc.).
I play the opposite as the last draw, so the last draw had the following 10-digit number:
The draw was 686 which is A1-B2. So, I will be playing A2-B1 this time. Sometimes doubles, and usually not pure unless it looks like a pure is due!
I also play the opposite High/Low. Since 686 is all High, I will play 2 Low/1 High. I don't play all High or all Low.
All of that boils down to 16 numbers for this draw in Texas:
