Aw, the old TTT system!
A guy showed me a version of TTT the day after I hit my license plate number (647) straight on the second ever Ohio Pick-3 drawing. He put the previous drawing in the middle row, subtracted 1 for the first digit on the top row, and added 1 for the bottom row. He added and subtracted 2 for the second position, and 3 for the third. His explanation was using a true TTT; vertically, diagonal, and horizontal creating 7 three digit numbers. Said it worked for the old numbers game. Can't back test anything from just two drawings so I decided to play my address instead.
TTT workouts are loosely based on the "magic squares", creates 9 digits on the board, and can have up to 84 three digit combos depending on how many repetitive digits. The probability using 9 different digits is 1 hit every 3 drawings so that type of TTT does produce hits, but for profitability one would have to play a less number of combos. From what I read in the other thread, there is no real system for choosing which combos to play.
By using the add 011 and 110 TTT method to the August 1 PA evening drawings, the results show 513, 634, and 147. By combining all those digits, there was only 1 three digit match in the month of August. (Which oddly enough was my three digit house address from 30 years ago!)
To get better results using the first drawing of the month, they would need a consistent method to create 5 or 6 different digits to use with a number like 513. From there they could use your A - I method to find the 4 or 5 most consistent digits over the past year and maybe create an interesting system.
To me playing the pick-3 is boring because of all the drawing between hits even with a above break-even system.
