- it needs the correct typing (with average matches <20% it's a big and main problem)
- there are important other factors besides types (average type description is not a concrete real human and with IR is the similar)
- it needs the usage of correct theory (but not random bs alike Reinin's) and correct its understanding (alike duals are described as not interesting on the 1st look in some texts)
- a part even of classical theory is wrong or doubtful, alike "polr" thought as the weakest function unlike at Jung

at 1st, it's important to understand correctly own type to notice how the typology works. with a videointerview you'd could to get opinions
