Say what now? That sentence doesn't mean anything.
You can see function use in micro-expressions. When you know which function is used, you can use the function through making that expression. You can also copy behaviours from people of the same type.
Since using dominant and auxiliary function gives energy and using tertiary and inferior function costs energy, there's a significant difference between using Te-Si and using Fi-Si for precise physical actions.
For example when I need it for example to take a shower, I make sure to have Fi expression - that is emoting.
I used to think that I'm an Introvert because I tended to massively use Si and Te in conversations. This made me exhausted in about an hour, slowed me down, made me stutter, etc :| . Then I got visually typed and I was watching videos with Emilia Clarke that is also an ENFP and I copied her extensive Fi use in conversations and also started using more Ne and suddenly I could meet someone and chat for hours O_O .
If I want to use Te in conversation, I also widen my eyes to activate Ne to fuel Te and talk faster too O_O .
Vague. Name an example if you're so interested in mistypes, but it is a moot point.
For example Laci Green mistyped as ENFP. She's not a Perceiver. Has no Perceiver hand movements. Saw two mistypes of this kind when I saw literally 6 specimen from their database.
Mistypes happen and as the typing method gets better, they will happen less and less.
If by better you mean more "convoluted".
I'm sure you never mistype anyone? Right?... lol
Besides, I doubt you're any good at typing.
I'm just a novice. I studied for 2 years but I had to scrap everything because the Pod'Lair database is full of mistypes, because its owner didn't bother to put due diligence into typing and would mistype people basing on wishful thinking instead of application of the typing method.
Have you ever seen primary Fe in action?
Also, the way you talk is annoying me, I'm going to add you to my ignore list.
