It seems the dots on some of these letters match up way to much to be accidental.

Could there be some kind of dot code like this being used?

What is the probability of so many dots from the lines matching up so well?

This is what I got from the first page of the death machine letter.

03, 05, 22, 28, 01, 19, 18, 26, 07, 14, 22, 31, 06, 23, 29, 11, 19, 24, 06, 13, 
16, 17, 24, 06, 08, 10, 24, 27, 30, 08, 12, 20, 25, 05, 15, 30, 02, 09, 20, 21

AZDecrypt shows a score of over 32,000 while working on this but I don’t know if that is simply because it is so short.

I don’t know if there is some easier way to look at the rest of the letters to see if this is prevalent.

Any ideas or suggestions?
