The chart simply illustrates the grades obtainable at tests. An attendance rate of 70% is a minimum eligibility requirement for tests. Dan and Gup grades are not themselves the object - they are a guide to progress only.
The official Kukkiwon policy is that 1st-5th Dan holders are "Masters", and 6th-10th Dan holders are "Grandmasters". You don't need to do anything to use these titles.
However, if you wish to be considered an "Instructor"
or "Master Instructor", you must take the Kukkiwon Instructor's Course
and pass the test. When you do that, you get a certificate certifying you
as an "Instructor" or a "Sabum". 1st-3rd Dan holders can take the course
and will receive a Certificate of Completion, but if you want that Instructor
certification, you must be a Kukkiwon 4th Dan holder and pass the test.
