There are way too many examples to list. I have taught many traditional stylists who believed that:
(1) In Pinan Sandan, both hands should actually be on your hips as the attacker comes with a right step-through punch to the ribs. Problem: (a) why in the world would you put both hands on your hips if someone was trying to take your head off? (b) I said "head" on purpose. If your hands are on your hips, wouldn't one think that the attacker just might try to punch you to the head area?
(2) Another similar example is when in traditional kata you execute a side kick with both hands at one hip. You couldn't imagine how many traditional style black belts have no clue why their hands do that. I have taught EPAK to many black belts from traditional schools (Shorin Ryu, Shorinji Ryu, Shotokan, Gojo Ryu, Wado Kai, ect.) and humbly asked them the application of these movements.
(3) Depending on the style, some call it Wansu, others Empi. In any case, the very first move starts with a right "downward block" as you drop all the way down to your right knee. The common application I see at MANY SCHOOLS: this move is to block a kick. My question: why drop down to your knee to block?
(4) In Sanchin, you tense, cross your arms in front of you, and bring your arms apart. I have seen at many seminars traditional style high-ranking black belts teach this for a two-handed lapel grab, in which you clear the opponent's arms off without any notion of a pin
I am just being honest, and I could list DOZENS of more examples.
