Above in response to " So you have discovered that even at world championships some people are not technically accurate?"This particular fault is due to poor systematization in the ITF, not inability of the practitioner.
The ITF conducts IICs particularly to alleviate the issue. Now if students and / or their instructors choose not to attend that is not the fault of the organization. History has shown that system works. Of course part of that historic proof long predates your existence..
