To find the hottest letters hitting look at the formulas for the last 20 drawings and then create two Reference Boxes using the letters as numbers.
For the first RB of 20 drawings look for the hottest letters in the 1st, 2nd, and 3rd positions, just like you would if they were digits.
Do a second RB with just the last 14 drawings, following the same process; line up the most frequent letters in the 1st, 2nd and 3rd positions.
What you will most likely find is that one letter will hit 3 times, in say the 1st position, and then you will have two or three other letters hitting just twice. For example, when looking in the first position for the 14 draw RB, the letter Q may hit 3 times and the letters B, C, and T may hit twice. So the order would be
Q
B
C
T
So you only include the letter if it hit 2 or more times; don’t include any letters that hit just one time.
For the 20 draw RB you will have more letters because you will have more letters hitting 2 or more times so the 20 draw RB will be bigger.
By comparing the RBs you did last night after the evening drawing you will quickly be able to see what digits are most likely to hit in the 1st, 2nd and 3rd positions today.
Also, I strongly recommend that you also do the regular 12 and 20 draw RBs.
With all this information in front of you (4 RBs) you will have be able to make an intelligent prediction of what numbers will hit next.
This is an entirely new process both for me and everybody else here so keeping a journal OR tracking this on a spreadsheet will be very useful. That is how I found out that the 20 and 14 draw grid RBs were more effective than the 10 draw one; because I notice it on my Excel spreadsheet after a few days of comparing the boxes with what actually hit.
I suggest you keep track of all this so see what works best in your state.
