Would love it if said cryptographer could stop posting back to back posts and consolidate them

Should be easy, right? lol!
Sorry about that, not big on forum etiquette, especially since I posted from phone.
What specifically does not work?
Deriving any sort of probability from prefixes to predict unchecked keys
unless you upgraded from tracking in excel

Never did, you must be confusing with how I was tracking the bruteforce operational data which was indeed in excel
Alas, you use probabilities during your search as well, you just use them differently.
I use them as confirmation, not prediction.
Yes, theorizing vaguely. Like in the case of Marilyn vos Savant vs. the mathematicians of the world, who were influenced by theories.
Would be great if there were less gibberish and more maths in your posts

But hey, you do you.
I can feel that my efforts here are not getting through, that's all right. Have fun with prefixes guys !
