Given that IP as a component of M. Ueshiba's aiki has been acknowledged by the Aikikai hombu:
- within that context, IP produces kuzushi on contact;
- the contact is literal, not philosophical or a feint; and
- atemi of all flavors are designed to disrupt attacks, and In jujutsu/taijutsu arts, which include aikido, disruption in the form of kuzushi is typically a primary or secondary objective of atemi.
Assuming this was the premise of Ueshiba's statement, that leaves the remaining question as: What comprises the other 1%?
