Identify the nature of the source
A regulation describes a test framework; a manual presents a method; a testimony reports an experience. None answers all the questions. A source close to an event can provide details without being neutral or complete. Note author, date, organization and purpose. A statement repeated on several sites is not necessarily confirmed by several independent documents.
A variation is not an automatic foul
Name, direction, rhythm or technical details may vary depending on the lines and programs. To compare, identify the exact passage and setting of each version. The existence of a variant does not allow all versions to be declared equivalent in an exam: the applicable program remains precise. The historical study and compliance with a current instruction answer two different questions.
Separate hypothesis and certainty
A name kata can receive several translations or explanations. A current application can be interesting without demonstrating the ancient use of the movement. Present what the document establishes, what you infer from it and what remains uncertain. Lack of evidence does not turn an attractive story into fact. It does not prohibit studying it, provided that it is named as a story or hypothesis.
Check information that may change
Programs, rules and administrative lists have versions. Consult the official publication in force for a procedure or competition. Keep the date of consultation and the link in order to find the context. For history, compare several types of sources rather than looking for a page that confirms your preference. Precision sometimes consists of saying that the available documents do not resolve the matter.
Check understanding
Does a modern application prove the historical intent of a kata?
See answer
No. Its educational relevance and historical attribution must be examined separately.
