No clue sorry
Your logic is fallacious, sorry. You correctly proved T is out, but you have a self-feeding loop with the SABOT thing. You need more words to fully demonstrate. For instance, basing just off those words:
TITLE = 0
SABOT = 2
TABOO = 3
Then in TABOO, it must be 3 of the last 4 letters. However, with just this info, it could be the A, B and the last O.
Another example of the fallacy: with just this info it could be the BOO from TABOO and the BO from SABOT.
If any letter proving is to be done, you need to bring in some extra words into the equation
