method to execute the kata  2) Specific 2 man drill sets  3)
Knowledge of the system's Dojo Kun and/or guiding principles  4)
Sparring (point, continuous, semi to full contact  5)
Positioning of blocks/kicks/stances  Now once an individual
starts his/her own dojo after achieving a certain rank in that
designated system they instruct how they feel is the best way to
distribute their knowledge. Some of their training methods may
be unorthodox. But they remain with the CORE basics of the
curriculum. Therefore everyone who sees them can understand that
