I've viewed one video so far. It helps me to validate the type calls I've already made and/or was uncertain about. I had not seen FiNe as verbally Te-factual before, and I'm not sure how Te relates in that respect.

This is one of the most ridiculous things that i have heard. People can have a whole range of expressions, and you guys are arrogant enough to think you can type someone just from a casual glance?
Sure you might be able to tell if they're I or E and possibly T or F (especially if you see their entire body and take into account everything). But I at least would not presume "yep, typical ESFP party girl"...even if she's dressed like a slut you can't be sure. You can quickly enough figure it out after actually talking to said person but there just isn't enough information available non-verbally.
