A respectable post thus far.
You're wrong in places, and your theory is bunk, but still a respectable effort.
You also agreed about Ni-Se, but then conveniently left out how this extends to Si-Ne, Te-Fi, and Fe-Ti.
Rather ironically, I think it's your lack of Te that is making you think you have Te.
Oh, well... c'est la vie...
Since you keep saying I don't have Te, I thought I'd post why I think I utilize Te...
In general, I have come to think of Te as an information gathering function outside of oneself (whereas Ti is inside one's own mind). When Te works most efficiently, as I perceive it would in a Te dom or aux, millions of bits of data can be churned through quickly and thoroughly, and along with this comes speedy organization because the data will be better retained if it is sorted in an orderly manner, and The Te-er also usually multitasks well because we see their mental processes running concurrently side-by-side and this manifests as being able to efficiently do several things at once. Contrast this to Ti, and I think of Ti doms and auxes as being able to multitask mentally very well; keep track of many processes or structures at once, which is what enables them to come up with elaborate architectures for inventing, programming, etc. In short, someone who multitasks well externally is most likely a Te-er, and one who multitasks well internally most likely a Ti-er....
I'll use my Hartzler book to outline my test results (with 1 to 5, most being able to do it comfortably):
"I objectively define the scope of the problems." 5
"I set or identify measurable goals for my efforts and the efforts of other people." 4
"I logically determine sequences and priorities needed to efficiently complete a task, or manage a program." 5
"I communicate concisely and logically the steps necessary to reach a goal or solve a problem." 4
"I use logic to convince others to work toward goals or to accept my position in a discussion." 3
"I objectively organize the external world (people, time, space, and things) to achieve measurable goals." 5
"I turn effective processes and procedures into performance standards, rules, and reguations." 4
"I evaluate performace against meaurable goals and standards." 4
I tested on all the functions in this book, and got this order: Ni>Fe>Te>Si>Ne>Fi>Ti>Se
So, if you see Ti in me, it's likely because that is the nature of a forum, and it's more difficult to assess Te on here, especially as a more inferior function...
