I know two Alpha NTs who are pretty OCD about certain things, in a way that I could see being related to Ti. The one I know better is an ILE, and he has all these rules for things, numbers being the one that I'm thinking of atm in [possible] relation to socionics...
For him, certain numbers are bad/absolutely unacceptable while others are good/permissable, and for very specific reasons - he has a system all worked out. Do other Alpha NTs, maybe specifically ILEs, identify w this at all? Is it Ti gone crazy?
